[flexcoders] RemoteObject Issue
I've been trying for the last few days to get RemoteObject to work,
but with little luck. I've searched this site, and have tried to
implement the examples found in developing rich clients with
macromedia FLEX. To make matters more confusing, I've also tried to
implement the command/control/delegate patterns that the above book
advocates.
Basically, I think the problem is that I'm not seeing the Java
classes I've created. Below are code snippets of (what I think) are
the relevant files.
### My Java classes ###
{TOMCAT-HOME}\webapps\flex\WEB-
INF\classes\com\foo\test\business\SiteMaintenanceDelegate.class
package com.foo.test.business;
import com.foo.test.vo.SiteKeywordVO;
public class SiteMaintenanceDelegate {
public SiteMaintenanceDelegate() {
}
public SiteKeywordVO reviewKeywords() {
SiteKeywordVO keywords = new SiteKeywordVO();
return keywords;
}
}
{TOMCAT-HOME}\webapps\flex\WEB-
INF\classes\com\foo\test\vo\SiteKeywordVO.class
package com.foo.test.vo;
import java.io.Serializable;
public class SiteKeywordVO implements Serializable {
public String[] keywords;
public void SiteKeywordVO() {
String[] keywords = {first agr, second agr, third agr};
}
}
### My RO definition ###
{TOMCAT-HOME}\webapps\flex\services\Services.mxml
mx:RemoteObject id=siteDataServices
source=com.foo.test.business.SiteMaintenanceDelegate
result=event.call.resultHandler(event)
fault=event.call.faultHandler(event)
showBusyCursor=true
mx:method name=reviewKeywords/
/mx:RemoteObject
### My ActionScript VO ###
{TOMCAT-HOME}\webapps\flex\sdm\com\foo\test\vo\SiteKeywordVO.as
class com.foo.test.vo.SiteKeywordVO {
public var keywords:Array;
public var _remoteClass;
public function SiteKeywordVO() {
_remoteClass=com.foo.test.vo.SiteKeywordVO;
}
}
### My testing mxml file ###
{TOMCAT-HOME}\webapps\flex\sdm\sdmUnitTest.mxml
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml;
xmlns:sdm=sdm.*
xmlns:services=services.*
sdm:SiteDataMaint/
services:Services id=myServices/
/mx:Application
### My SiteDataMaint component ###
{TOMCAT-HOME}\webapps\flex\sdm\SiteDataMaint.mxml
... //just the script part
mx:Script
![CDATA[
import sdm.business.*;
import sdm.commands.*;
import sdm.control.*;
import com.foo.test.vo.*;
import mx.controls.Alert;
public function initApp() {
var controller = new SDMController;
}
]]
/mx:Script
...
The SDMController class seems to be working correctly.
### My Delegate class ###
{TOMCAT-HOME}\webapps\flex\sdm\business\SDMDelegate.as
... //just the constructor
public function SDMDelegate(responder:Responder) {
this.service =
mx.core.Application.application.myServices.siteDataServices;
Dumper.dump(service);
this.responder = responder;
}
I think this is where the problem is. When I dump 'service' (via
Flex Trace Panel), I get 'undefined'.
I really have no idea where to go from here. I've tried turning on
all debug stuff, used NetConnectionDebugger, use Flex Trace Panel...
nothing on all accounts.
Thanks for any suggestions you may have!

[flexcoders] Re: RemoteObject Issue
I think I have. Below is part of the file ReviewKeywordsCommand.as,
which is the result handler from the RO call.
import com.foo.test.vo.*;
...
public function onResult( event ) : Void {
var sk:SiteKeywordVO = (SiteKeywordVO) event.result;
mx.core.Application.alert(Passed in + sk);
}
...
I just wanted to throw an Alert for now That way I knew
something was coming in. eventually, it will populate a datagrid.

[flexcoders] Re: RemoteObject Issue
Hmm
I replaced the service assignment with:
this.service = parentApplication.myServices.siteDataServices;
But I get the following error:
There is no property with the name 'parentApplication'.
Looking at the docs, parentApplication looks like it's intended to
walk up the tree of multiple application nested within themselves. I
don't think that applys to this case since I only have 1 mxml file
with the mx:Application tag. Please correct me if I've
misunderstood this.
Thanks,

[flexcoders] Re: RemoteObject Issue
I tried to dump myServices via:
codeDumper.dump(mx.core.Application.application.myServices);/code
during the Delegate constructor, and it came up 'undefined'.
I tried a creationComplete and an Initialize event to dump
siteDataServices upon startup of the main mxml file. Both had this
to say:
[INFO]: (Object)
log: (Object)

Looks like it's available at both initialization and creationComplete

I'm curious why the examples taken from the books website would prove
to be this difficult to implement.
When you say pass the service to your delegate constructor as a
parameter, do you mean as a string? Like the following:
public function ReviewKeywordsCommand() {
this.delegate = new SDMDelegate( this, mx.core.Application.\
application.myServices.siteDataServices );
}
sorry if these are really basic questions, but I'm new to RIA
development.

[flexcoders] Re: RemoteObject Issue
How crazy is this! I took your advise and moved a few things
around. In my Unit test file I changed it to:
mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml
xmlns:sdm=sdm.*
xmlns:services=services.*
services:Services id=myServices/ ---changed
sdm:SiteDataMaint/ ---changed
/mx:Application
Basically just swapping the order of the services and sdm tag made it
work.
Thanks for all your efforts Doug!

It seems like siteDataServices hasn't been created at the time the
SMDelegate constructor is being called. You'll need to dig through
your code to find out why, e.g. check where you're calling
ReviewKeywordsCommand(), and possibly call the constructor at some
other point when you know the remote object has been created.
Regarding parameter passing, the constructor example you gave is
exactly what I had in mind. The value you're passing isn't a string
though, it's a reference to the RemoteObject that you gave the id
siteDataServices to. Personally, I'd probably pass the service
as a
parameter, but as long as the delegate constructor is called only
after you know the service object exists, either way should work.
I hope this helps, and another thing to note is that the work you're
doing now to implement these design patterns will pay off down the
road - especially if you're implementing a large-scale app.

[flexcoders] Re: Box layout question - two children with 100% width
--- In flexcoders@yahoogroups.com, Collin Peters [EMAIL PROTECTED] wrote: I am having some layout problems in my app. It is fairly complex with many levels of nesting of panels, viewstacks, boxes, etc... In the end I have an HBox with a width of '100%'. I assume this means take up 100% of the width of the parent. Inside the HBox I have three components. A VBox on either side, and a VRule in the middle (as a separator line). I want each of these VBoxes on the side to take up 50% of the parent. If their content doesn't fit, then scrollbars should appear in that VBox. What I am finding is that I cannot get this to happen. If the content of the left VBox is larger than 50%, it just expands and takes up as much room as it pleases, forcing scrollbars onto a parent way up in the stack. How do I force two children of a box to take up 50% of the parent? I have tried 100% for the children and 50% for the children and neither seems to make a difference -- Collin Peters Lead Software Developer InTouch Technology I would try using a Canvas to surround the 2 VBoxes and the VRule.

[flexcoders] Nested Repeater Issues
I have a Repeater of CheckBoxes, which may or may not have a sublayer
of CheckBoxes. It should look something like:
[] archive 1
[] archive 2
[] dataSource 1
[] dataSource 2
[] dataSource 3
[] archive 3
By default all CheckBoxes are unselected, and any
sublayer CheckBoxes are not enabled. If you select a CheckBox(archive
2) that has sublayer CheckBoxes (dataSource 1- 3), they are enabled.
If you unselect a CheckBox that has sublayer CheckBoxes, they are
disabled and unselected.
I'm using the Cairngorm framework, so the call results from the
database are returned to my model. This model is used as the
dataProvider for the Repeater.
The issue is that I can not update my model and have the sublayer
Repeater update properly. For example, if there are three sublayer
CheckBoxes (like above), selecting the parent CheckBox (archive 2)
will enable only the first 2 sublayer CheckBoxes (dataSource 1 2).
Then deselecting the parent CheckBox will disable the first 2 sublayer
CheckBoxes, but enable the third (dataSource 3). From this point on
the enabled property for dataSource 12 will be in a opposite state
from dataSource 3.
Below are code snippets:
Library.mxml:
mx:Repeater id=archiveRepeater
dataProvider={__model.archiveElements}
mx:CheckBox id=archive
label={archiveRepeater.currentItem.archiveName}
click=__model.archiveChanged(event)/
mx:Repeater id=dataSourceRepeater
dataProvider=
{archiveRepeater.currentItem.archiveDataRepositories}
mx:CheckBox id=dataSource
label={dataSourceRepeater.currentItem.repositoryName}
enabled={dataSourceRepeater.currentItem.enabled}
selected={dataSourceRepeater.currentItem.selected}
click=__model.dataSourceChanged(event)
/mx:CheckBox
/mx:Repeater
/mx:Repeater
LibraryModel.as:
public function archiveChanged( event:MouseEvent ):void
{
var selectionChoice:Boolean = event.target.selected;
var selectionName:String = event.target.label;
var al:ArchiveLocation =
ArchiveLocation(event.target.getRepeaterItem());
al.selected = selectionChoice;
// Go through any data repositories
// and toggle their enabled property
if (al.archiveDataRepositories != null)
{
var adr:Array = al.archiveDataRepositories;
if (selectionChoice == false)
{
// Deselect and disable all CheckBoxes
for (var i:uint = 0; i adr.length; i++)
{
// Update the model
adr[i].selected = false;
adr[i].enabled = false;
}
else
{
// Enable all CheckBoxes
for (i = 0; i adr.length; i++)
{
adr[i].enabled = true;
}
}
}
}
}
As you can tell, there are ValueObjects that store the enabled and
selected attributes for the dataSource CheckBoxes.
What's even weirder, is that the ValueObjects that make up the
dataProvider for the Repeater are updated correctly (their selected

in a state that is opposite of the other grouped sublayer CheckBoxes.
I've gotten around this by directly updating the display by using:
event.target.document.dataSource[i][j].enabled = false;
But I don't want to rely on this as it will cause issues later on.
I feel that I should be able to update the dataProvider for the
various Repeaters and this should update the display properly. Any
suggestions would be greatly appreciated.

I have a Repeater of CheckBoxes, which may or may not have a sublayer
of CheckBoxes. It should look something like:
[] archive 1
[] archive 2
[] dataSource 1
[] dataSource 2

[] archive 3
By default all CheckBoxes are unselected, and any
sublayer CheckBoxes are not enabled. If you select a CheckBox(archive
2) that has sublayer CheckBoxes (dataSource 1- 3), they are enabled.
If you unselect a CheckBox that has sublayer CheckBoxes, they are
disabled and unselected.
I'm using the Cairngorm framework, so the call results from the
database are returned to my model. This model is used as the
dataProvider for the Repeater.
The issue is that I can not update my model and have the sublayer
Repeater update properly. For example, if there are three sublayer
CheckBoxes (like above), selecting the parent CheckBox (archive 2)
will enable only the first 2 sublayer CheckBoxes (dataSource 1 2).
Then deselecting the parent CheckBox will disable the first 2 sublayer
CheckBoxes, but enable the third (dataSource 3). From this point on
the enabled property for dataSource 12 will be in a opposite state
from dataSource 3.
Below are code snippets:
Library.mxml:
mx:Repeater id=archiveRepeater
dataProvider={__model.archiveElements}
mx:CheckBox id=archive
label={archiveRepeater.currentItem.archiveName}
click=__model.archiveChanged(event)/
mx:Repeater id=dataSourceRepeater
dataProvider=
{archiveRepeater.currentItem.archiveDataRepositories}
mx:CheckBox id=dataSource
label={dataSourceRepeater.currentItem.repositoryName}
enabled={dataSourceRepeater.currentItem.enabled}
selected={dataSourceRepeater.currentItem.selected}
click=__model.dataSourceChanged(event)
/mx:CheckBox
/mx:Repeater
/mx:Repeater
LibraryModel.as:
public function archiveChanged( event:MouseEvent ):void
{
var selectionChoice:Boolean = event.target.selected;
var selectionName:String = event.target.label;
var al:ArchiveLocation =
ArchiveLocation(event.target.getRepeaterItem());
al.selected = selectionChoice;
// Go through any data repositories
// and toggle their enabled property
if (al.archiveDataRepositories != null)
{
var adr:Array = al.archiveDataRepositories;
if (selectionChoice == false)
{
// Deselect and disable all CheckBoxes
for (var i:uint = 0; i adr.length; i++)
{
// Update the model
adr[i].selected = false;
adr[i].enabled = false;
}
else
{
// Enable all CheckBoxes
for (i = 0; i adr.length; i++)
{
adr[i].enabled = true;
}
}
}
}
}
As you can tell, there are ValueObjects that store the enabled and
selected attributes for the dataSource CheckBoxes.
What's even weirder, is that the ValueObjects that make up the
dataProvider for the Repeater are updated correctly (their selected
and enabled properties), but the last CheckBox of any sublayer remains
in a state that is opposite of the other grouped sublayer CheckBoxes.
I've gotten around this by directly updating the display by using:

[flexcoders] Getting Parent's Style
I'm converting some Flex1.5 code to flex 2.0. One of the classes (a commonly used custom component) uses the following to set the background color to that of the parent container: __labelCanvas.setStyle(backgroundColor)=_parent.getStyle(backgroundCo\ lor); This doesn't work in Flex2.0, nor does parent.getStyle(backgroundColor); How can I get a style attribute of a parent container? BTW, I can't just let it be transparent because I need to obscure some drawn graphic elements of the parent, but I want __labelCanvas to have the same background color as the parent. Also, the parent might not always be the same color, else I would set a CSS descriptor for it. Thanks, GT
[flexcoders] Re: Getting Parent's Style
Alex,
Thanks for the heads-up. I was on that path as I was looking up what
type 'parent' was.
Actually, I couldn't just assume parent would have backgroundColor set.
Sometimes it was 2 or 3 parents up the chain where backgroundColor was
set. So, I ended up with this:
code
var bgColor:* = undefined;
var currentParent:* = this.parent;
// This should loop through until it hits the top-most application.
// Hopefully this will prevent infinite looping.
while(currentParent is IStyleClient) {
bgColor = IStyleClient(currentParent).getStyle(backgroundColor);
if (StyleManager.isValidStyleValue(bgColor)) {
__labelCanvas.setStyle(backgroundColor, bgColor);
break;
}
else {
currentParent = currentParent.parent;
}
}
/code
I typed bgColor as * because if I used uint, it always returned 0 (zero)
if getStyle() didn't find anything. This caused isValidStyleValue() to
return a false true since 0 is a valid uint value.
Thanks for the help,
GT

[flexcoders] Does Drag Drop Only Update the DataProvider?
I have a DataGrid that has a dataProvider bound to an ArrayCollection.
code
mx:DataGrid id=dgEmployees
dataProvider={__employees}
...
/code
I also have another DataGrid (dgAllEmployees) that is within a popup,
which I use as a source for Drag Drop operations to populate the
dgEmployee dataGrid.
What I've noticed is that when I drag drop employees from the all
employees DataGrid to the employees DataGrid, it seems to only
update the dataProvider of dgEmployees, and not the ArrayCollection
__employees. Why is this?
Below is a snip of my drag drop code where it actually copies the
data. This is a generic method that is used all over the application.
code
public static function doDragDrop( event:DragEvent ):void
{
// Prevent the default event from happening.
event.preventDefault();
// Get drop target
var dropTarget:DataGrid = DataGrid(event.currentTarget);
// Get the dragged items from the drag initiator.
var dropItems:Array = event.dragSource.dataForFormat(items) as Array;
// Add each item to the drop target.
for (var i:uint = 0; i dropItems.length; i++)
{
var dest:IList = IList(dropTarget.dataProvider);
if (!contains(dest, dropItems[i]))
{
dest.addItem(dropItems[i]);
}
}
}
/code
I think that I had event.preventDefault(); in there because it was
putting 2 of each dropped item in the dgEmployee DataGrid. Might this
be messing something up?
Also, contains() is a custom method to compare the source items to
what's in the target's list to prevent duplicates. Is there a better
way to do this?
Thanks in advance.

[flexcoders] Re: Does Drag Drop Only Update the DataProvider?
I don't have the code in front of me right now, but to be more precise,
dgEmployees is not
broadcasting a change event upon a DD action. I want dgEmployees to broadcast
an
event every time there is a change to the DataGrid. The dgEmployees DataGrid
has a
change event method defined, somthing like:
code
mx:DataGrid id=dgEmployees
dataProvider={__employees}
change=broadcastEvent(event)
...
/code
The broadcastEvent() method constructs a custom event containing the number of
elements in the DataGrid, and then dispatches it to be used elsewhere.
Now, as I type this, I see that I might have keyed off the wrong event,
change. Not sure if
that is broadcast upon a change in the dataProvider, BUT I had been working on
this code
previously (converting to Flex 2.0), and I believe that I saw this same issue.
I noticed that when I used the debugger to step throught the doDragDrop()
method, I was
seeing that only the dataProvider was being updated, and not the
ArrayCollection. I can't
verify this until Monday (5/21), but I'm almost 100% sure this is what I saw.

[flexcoders] Re: Does Drag Drop Only Update the DataProvider?
collectionChange doesn't appear to be a valid DataGrid event, but I
tried dataChanged, added, add, valueCommit, and updateComplete. None
of these did what I wanted, and actually, I have verified that the
__employees ArrayCollection does not update after a DD event.
Looking through everything in debug mode, I'm seeing that the
dataProvider of the DataGrid is updated after DD, but not the bound
variable __employees.
I wonder if it's how I declared the variable? I did it like so:
code
[Bindable]
private var __employees:ArrayCollection;
public function get employees():ArrayCollection {
return __employees;
}
public function set employees( employees:ArrayCollection ):void {
if (employees != null) {
__employees = employees;
}
}
/code
Maybe I should just make it public? Nope, that didn't work.
I'm also wondering if the event.preventDefault(); is messing
something up. Nope, that just prevents the the base class ListBase
from doing it's DD handling. Since this doesn't check for
duplicates, I don't want to use it.
I'm not sure what to do

[flexcoders] Re: Does Drag Drop Only Update the DataProvider?
I read (Migrating Applications to Flex 2 by Adobe, page 108) that if
you have private variables with getter/setter, you can omit the event
name as the compiler would automatically generate an event named
propertyChanged. What that example shows that I didn't do is it put
the [Bindable] metadata tag before the getter method, not the variable
declaration. I'll change that in the future.
Regarding your last statement, I would like to think that the bound
ArrayCollection would update if you specifically update the
dataProvider of the DataGrid, but according to what I'm seeing in the
debugger, that isn't the case. I wish it were... It would've made my
life a lot easier.
BTW, thanks for your help.

I thought there was a warning for binding to private, but maybe we got

Binding is one way, but if the dg is bound to employees, the underlying
array that got passed into the ArrayCollection should get modified when
you drop into the dg.

[flexcoders] Nested classes picking up CSS
Here's the basic setup. On display 1 there is Panel A, on display 2

I tried something like:

My basic goal is to have common components take on a different style
depending on the parent it's contained within. I would like to set
the parents style via styleName and have that propagate down through
the children through something like:
.styleA{}
.styleA.Panel{}
.styleA.DataGrid{}
.styleA.CustomClass{}

I'm trying to figure out how to make a custom slider... at least I think it's going to be a custom slider. What I want is a slider that allows me to select a time range based on a 24 hour clock. Here are the requirements: -Two thums on the slider(min, max) -Min value of 00:00:00 -Max value of 23:59:59 The desired behavior is that if you move the min thumb to the right, it will increment the min value based on a clock (base-60 I guess). Also, moving the max thumb to the left will decrement the max value accordingly. The end result will be a time range (i.e. used to select all occurances of event X that lasted from 5 minutes to 4 hours and 30 minutes). I haven't been able to find anything in the API that seems to scream Go in this direction, so I was hoping someone might be able to clue me in.

[flexcoders] AS to Java Translation Problems
ENV: Flex 1.5 served from WebSphere6.1
All of our Java objects used to use java.util.Date for date
properties, but we had to convert them to java.util.Calendar. Since
Flex 1.5 doesn't support mapping from AS Date to Java Calendar and
vise versa, I came up with another way of doing it. Obviously it
doesn't work, or else I wouldn't be here! :-P
Here is some code:
WorkgroupVO.as - This is the object I'm trying to send to Java
import com.beans.common.*;
class com.beans.WorkGroupVO {
public var workGroupID:String;
public var startDate:CalendarVO;
public var endDate:CalendarVO;
static var rc:Boolean = Object.registerClass(com.beans.WorkGroup,
com.beans.WorkGroupVO);
public function WorkGroupVO(){}
}
CalendarVO.as - My ActionScript Calendar object
class com.beans.common.CalendarVO {
public var time:Date;
static var rc:Boolean = Object.registerClass(java.util.Calendar,
com.beans.common.CalendarVO);
public function CalendarVO(){}
}
Here's how I use the WorkgroupVO object that is returned from Java.
This works. I'm populating a DateField with the supplied dates.
public function set wg( wg:WorkgroupVO ):Void {
...
availability.startDate = wg.startDate.time;
availability.endDate = wg.endDate.time;
...
}
To save this information for an update, I use the following code:
public function saveWorkgroup() {
var newWg:WorkgroupVO = new WorkgroupVO();
newWg.groupName = tiGroupName.text;
// Create a new CalendarVO and set it's time property to the
selectedDate.
var startCal:CalendarVO = new CalendarVO();
startCal.time = dfStartDate.selectedDate;
newWg.startDate = startCal;
var endCal:CalendarVO = new CalendarVO();
endCal.time = dfEndDate.selectedDate;
newWg.endDate = endCal;
...
// Pass newWg to my RemoteObject at this point
}
This does create a Calendar object that is mapped to
java.util.Calendar according to Service Capture, but this is the
error I'm getting:
(Message #0 targetURI=/7/onStatus, responseURI=null)
(Object #0)
code = Server.Processing
description = Cannot invoke method 'createWorkgroup'.
type = flashgateway.GatewayException
rootcause = (Object #1)
code = null
description = Could not set object null on class
com.beans.Workgroup's method setStartDate
type = flashgateway.translator.ASTranslationException
level = error
details =
flashgateway.translator.ASTranslationException: Could not set object
null on class com.beans.Workgroup's method setStartDate
at
flashgateway.translator.decoder.JavaBeanDecoder.decodeObject
(JavaBeanDecoder.java:99)
I believe I usually get this type of error when my AS objects don't
jive with the Java Bean. Do you think my AS Calendar object isn't
mapping to the Java.util.Calendar class properly? If this were true,
then why do I receive data correctly?
Also, for debugging purposes I have gateway-config logging set to
Debug, and I'm using Service Capture to see the flow of data back and
forth. I wish there was more detail coming back from the Flex
Gateway in reguard to the actual mapping process (I saw there is a
isDebug property in one of the flexgateway jars, but it's private).
Anyone know of a way to get more information out of the FlexGateway???
Thanks in advance,
Geoff

[flexcoders] Re: AS to Java Translation Problems
Doug,
Our java objects need to have dates set to type Calendar. So are you
suggesting that my ActionScript value objects have a setter/getter?
Something like:
class com.beans.WorkGroupVO {
public var workGroupID:String;
public var startDate:Date;
public var endDate:Date;;
static var rc:Boolean = Object.registerClass(com.beans.WorkGroup,
com.beans.WorkGroupVO);
public function CalendarVO() {}
public set startDate( num:Number ):Void {
startDate = new Date(num);
}
public get startDate():Number {
return startDate.getTime();
}
I don't think I quite get your meaning.
Thanks,
Geoff

Geoffrey, you may or may not find this to be helpful but I've found
it much easier to deal with times as longs than as instances of

with
date.getTime() or calendar.getTime().getTime(), and longs fit
nicely
on the AS side as well. When displaying time values in datagrids,
for instance, I needed the timelong instead of the Date object in
order to preserve the default sort behavior regardless of what type
of string formatting was applied to the date.

[flexcoders] Re: AS to Java Translation Problems
As a follow-up, I was on track with my original thoughts. The error
in the ActionScript code was registering CalendarVO to
java.util.Calendar. It should have been
java.util.GregorianCalendar. java.util.Calendar is an abstract class
and doesn't have a public constructor.
Would've been nice if I picked up on this earlier instead of banging
my head against the monitor!

I've looked around and I can't find a solution that helps me.
I'm
new to Flex, so I would appreciate a detailed explaination since
I'm obviously not getting it.
Thanks,

Sorry, I posted some wrong code. I have fixed it above, but I
still
get the same error.
Thanks,

[flexcoders] Deliver compiled actionscript

Is there a way to compile the actionscript or convert it to a format that can not be reverse engineered? Thanks. Which version of Flex? You could do some mild obfuscation in 1.5, but not easily. There are no tools out yet for reverse engineering Flash 8.5 applications. Its a rather more difficult process. Still possible, though. You could fairly easily encrypt your proprietary executable code in a SWF, then load it on the client as an opaque blob of binary data, decrypt it on the client, then call Loader.loadBytes to run it. Since the decryption code would be in the client in the clear, you'd need to send the key over SSL or something. They could still intercept things, but it would be much much more difficult. Sadly, you've got a bunch of code to write to do this, we don't supply a code encryptor. The bits are in the client's hands, and they need some way of decrypting them to run the bits, so fundamentally, no matter how many levels of encoding you add, you're just looking at obfuscation. -rg Hmmm Not the answer I was looking for, but similar to what I was thinking. BTW, We're using Flex 1.5.

[flexcoders] Item Renderer Not Updating
I have a List that is bound to an ArrayCollection. If I programaticly
update the ArrayCollection, the itemRenderer fails to update as well.
mx:List id=userList
dataProvider={__resourceModel.userSummaries}
selectable=false
itemClick=onItemClick(event)
itemRenderer=mx.controls.CheckBox
width=100% height=100%/
__resourceModel.userSummaries is an ArrayCollection of
ResourceItemModels which looks like:
public class ResourceItemModel implements ModelLocator
{
public var username:String;
public var firstName:String;
public var lastName:String;
// These are used by an itemRenderer
public var label:String;
public var selected:Boolean;
}
The List is a list of CheckBoxes with the username as the label. When
someone selects one of the CheckBoxes, it go off and sets the
'selected' property of the specific ResourceItemModel to true. This
part works just fine.
After a certain user gesture, I want to set all selections back to
false, then reselect any CheckBox selections that may have existed.
This information comes from another model. The resetting of the
CheckBoxes is in a loop that does:
ResourceItemModel(userSummaries[i]).selected = false;
This properly sets the models selected property to false, but the view
does not update (ie. the CheckBox is still selected).
How do I update the itemRender after I programmaticly update the
dataProvider?
Thanks,
Geoff

[flexcoders] Re: Item Renderer Not Updating
I went and created a component as the itemRenderer, like this:

I think the key was to NOT use 'selected' as a property in the model,
and I also added userList.invalidateList() before the section of code
that sets all the CheckBoxes back to being deselected.

The ResourceModel and ResourceItemModel classes are [Bindable]. Is
that what you're talking about?
Also, I was thinking that the 'selected' property of
ResourceItemModel
is not used for the 'selected' property of the CheckBox in the
itemRenderer. The 'label' property of the model seems to work,
but is
'selected' not the appropriate variable to use? Should it be
something like 'data' perhapse?

[flexcoders] BlazeDS - Unknown destination error
I'm trying to get BlazeDS working with our existing Flex application. When the application starts and tried to subscribe to a publisher, I get the following error: [MessagingError message='Unknown destination 'userTopic'.'] at mx.messaging.config::ServerConfig$/getChannelSet() [C:\dev\enterprise_bali\frameworks\mx\messaging\config\ServerConfig.as:224] ... I have the topic defined in my messaging-config.xml file like this: destination id=userTopic/destination Not really sure what the deal is. I've converted our app to use the Flex 3 plugin for Eclipse, and that seems OK (not sure if I really needed to do this). The only thing I see is that the properties of the main flex project say Project is being compiled with Flex 3.0, but server has Flex 2.0.1 in the Flex Compiler section. Ummm, say what? Any help would be appreciated.
[flexcoders] Re: BlazeDS - Unknown destination error
I hate to say it, but I don't know how to do any of that.
-- Point 1 --
[point] your compiler at the services-config.xml which defines those
destinations
Here are a couple lines of debug output from the console. I think I'm
pointing to the correct config files.
[Flex] [Configuration] BlazeDS - Community Edition: 3.0.0.353
[Flex] [Configuration] Endpoint my-streaming-amf created with
security: None
[Flex] [Startup.Destination] Destination with id 'userTopic' is
ready (startup time: '0' ms)
[Flex] [Startup.Service] Service with id 'message-service' is ready
(startup time: '0' ms)
[Flex] [Startup.MessageBroker] MessageBroker with id '__default__'
is ready (startup time: '407' ms)
So to me, that part of the configuration is correct.
-- Point 2 --
define a channel set on the client and set the channelSet property on
your service
This is my code in main.mxml to define my consumer:
mx:Consumer id=userConsumer destination=userTopic
message=onUsersFeed(event)/
And the corresponding code in AS to subscribe to the destination.
public function onCreationComplete():void
{
// Subscribe to destination
userConsumer.subscribe();
}
Am I doing something wrong here? I basically took this from one of
the BlazeDS samples.
-- Point 3 --
You can see what destinations are getting compiled into your app via
the static variable: flex.messaging.config.ServerConfig.xml
I don't know how to access this variable. Is this a Java variable?
Thanks for the help, and sorry for me being so dense.

[flexcoders] Re: BlazeDS - Unknown destination error - SOLVED
I honestly don't know how I fixed it. I reinstalled Apache, and the Flex 3 Eclipse plugin. Then ripped out every instance of Flex 2 I could find except for the flex-bootstrap-2.0.1.jar file (if I did that, nothing worked). Now I can receive a message published from our J2EE server. Thanks to Jeff for the help. Geoff --- In flexcoders@yahoogroups.com, Geoffrey [EMAIL PROTECTED] wrote: I'm less than thrilled with BlazeDS right now. running their canned examples is no problem, but try to integrate it into your app and it's a bitch! Our environment is Eclipse 3.2.2, Apache Tomcat 5.5.20, Flex Builder 3 Plug-in, Maven 2.0.5, WST 1.something. Regarding Point 1 below, I fixed my compiler argument. For the main Flex application, I navigated to the Flex Compiler properties and entered -services C:\workspace-blazeDS\flex\src\main\webapp\WEB- INF\flex\services-config.xml -locale en_US for my Additional Compiler Arguments. Previously, I had it pointing to a different workspace. On that same screen I see a warning: Project is being compiled with Flex 3.0, but server has Flex 2.0.1. How do I check what version of Flex the server is using? I've gone through and removed all Flex 2.0.1 related jars, but I seem to need the flex-bootstrap- 2.0.1.jar or else I get a bunch of errors upon server startup. Is this why I'm getting the warning message above? Is this why I can't seem to pass messages with BlazeDS? Is there a flex-bootstrap-3.0.jar? Not in the flex 3 distribution that I have. It was real nice of Adobe to clue us into the fact that BlazeDS requires Flex3. The only reason that I know this is because someone else had some problems and Jesse Warden found out from one of the Flex engineers that Flex 2.0.1 does not support BlazeDS. What other requirements are there that we don't know about? Sorry if I'm being harsh, but I've been screwing around with this for the last WEEK and can't get it to work. It shouldn't be this difficult. --- In flexcoders@yahoogroups.com, Jeff Vroom jvroom@ wrote: Sorry for the terse description - it's been a little busy here! For Point 1, the stuff you have there looks like the server itself is starting up fine. The issue is that when you compile your SWF, the tool you use to compile your SWF also should refer to the services-config.xml file. If you are using flex builder, there is a setting for that in your project properties. If you are requesting the MXML file directly from the browser (where the server compiles the mxml file to produce the SWF), this is in your flex-config.xml file. If you are compiling using ant or the command line compiler there is a -services option to the compiler. For Point 2, since you do not set the channelSet property on your Consumer component, you need to follow the step in point 1. There is another option where the client downloads the configuration for your destination from the server when it connects. But for that to work, you need to specify the URL to the server so it can connect in the first place. You do that with the channelSet property. For Point 3, you can see this by adding the MXML tag: mx:TraceTarget/ If you are using the debug player, you'll see some diagnostics in the flashlog.txt file. That gets buried in the user's home directory on windows under application data/macromedia/flash player/logs. Make sure you have the debug player though since the release player doesn't output trace information. You can also get to this property directly in actionscript with: import flex.messaging.config.ServerConfig; trace(ServerConfig.xml); Jeff From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Geoffrey Sent: Thursday, February 14, 2008 1:37 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: BlazeDS - Unknown destination error I hate to say it, but I don't know how to do any of that. -- Point 1 -- [point] your compiler at the services-config.xml which defines those destinations Here are a couple lines of debug output from the console.

[flexcoders] BlazeDS Subtopics from Java
I see plenty of examples of how to do subtopics all from MXML/AS
code, but how to you create a message in Java that has a subtopic?
Here are some code snippets:
:::messaging-config.xml:::
destination id=siteMessages
properties
server
max-cache-size1000/max-cache-size
allow-subtopicstrue/allow-subtopics
subtopic-separator./subtopic-separator

/destination
:::main.mxml:::
mx:Script
public function onCreationComplete():void {
siteMessagesConsumer.destination = siteMessages;
siteMessagesConsumer.subtopic = *;
siteMessagesConsumer.subscribe();
}
public function onSiteMessages( event:MessageEvent ):void {
trace(Got it!);
}
/mx:Script
mx:Consumer
id=siteMessagesConsumer
message=onSiteMessages(event)/
:::MyDelegate.java:::
private void sendFlexMessage() throws MyException {
MessageBroker msgBroker = MessageBroker.getMessageBroker(null);
String clientID = UUIDUtils.createUUID();
// Generate a message
AsyncMessage msg = new AsyncMessage();
msg.setDestination(siteMessages.allUsers);
msg.setClientId(clientID);
msg.setMessageId(UUIDUtils.createUUID());
msg.setTimestamp(System.currentTimeMillis());
msg.setBody(getSomeObject());
// Send a message
msgBroker.routeMessageToService(msg, null);
}
The sendFlexMessage() method is called from somewhere else. This
worked when my destination was just siteMessages. But I want to
send subtopics
like siteMessages.allUsers, siteMessages.allTeams, etc. I
looked at the Java API for this stuff and saw nothing that jumped
out like a setSubTopic() method, so I assumed that it was as simple
as setting the destination to something.something. That seems to
be the way they did it in the MXML/AS examples I saw, but when I try
to send the message I get an error saying that there is
no siteMessages.allUsers destination.
Any suggestions would be appreciated.
[flexcoders] Plot Graph and One Plot Point
I have a PlotChart that uses a DateTimeAxis for the x, and a LinearAxis for the y. I get something strange when there is only one point to plot. The point renders fine on the chart, but the horizontal axis renderer only shows one date (1/1/70), and that's not the date of the plot point. I would imagine that it should be the same date as the plot point. Here's my horizontal axis renderer code: mx:horizontalAxis mx:DateTimeAxis baseAtZero=false dataUnits=milliseconds labelUnits=days/ /mx:horizontalAxis mx:horizontalAxisRenderer mx:AxisRenderer visible=true labelRotation=0 canStagger=false canDropLabels=true showLine=true/ /mx:horizontalAxisRenderer Any ideas? Thanks, Geoff
[flexcoders] Zero line drawn on plot chart

[flexcoders] Re: BlazeDS Subtopics from Java - SOLVED
Trial and error solved this since I couldn't find any examples or
documentation.
The AsyncMessage object in the Java class needs to be set up like
this:
...
msg.setDestination(siteMessages);
msg.setHeader(DSSubtopic, siteData.userSummary);
...
siteMessages is the name of the destination set up in messaging-
config.xml. You also need to specify a DSSubtopic in the
AsyncMessage header.
The Consumer(from AS or MXML) needs to have:
siteMessagesConsumer.subtopic = siteData.*;
I found out that you can't just specify userSummary in the
DSSubtopic and set siteMessagesConsumer.subtopic = '*'. This
resulted in an error when trying to actually publish a message. The
subtopic must be nested, siteData.*.
Hope this helps someone else.

The sendFlexMessage() method is called from somewhere else. This
worked when my destination was just siteMessages. But I want to
send subtopics
like siteMessages.allUsers, siteMessages.allTeams, etc. I
looked at the Java API for this stuff and saw nothing that jumped
out like a setSubTopic() method, so I assumed that it was as
simple
as setting the destination to something.something. That seems
to
be the way they did it in the MXML/AS examples I saw, but when I
try
to send the message I get an error saying that there is
no siteMessages.allUsers destination.
Any suggestions would be appreciated.

[flexcoders] Convert Flex App to AIR App
I have an existing Flex app... a pretty complex one. Multiple projects, J2EE backend, RemoteObject calls, BlazeDS messaging with JMS, etc, etc. What's the best way to convert this existing app to an AIR app? Would it be possible to just reference the SWF from the main Flex app? I'd rather not copy the entire main flex project into the newly created AIR package. That would be a lot of duplicate code. Thanks, Geoff
[flexcoders] Re: Convert Flex App to AIR App
Thanks Robert, looks interesting! The Ant idea was interesting too, but I have a feeling that in the future we'd want to use some AIR-specific APIs, and I don't think an Ant task could accomplish that. The pattern that article outlines sounds just right for the job. ~Geoff --- In flexcoders@yahoogroups.com, Robert Cadena [EMAIL PROTECTED] wrote: Hi Geoff, Here's a link that should be helpful: http://www.adobe.com/devnet/air/flex/articles/flex_air_codebase.html Some time ago I dealt with the same issue on Flex 2 beta. Basically, the way I dealt with it was to extract all the functionality into a Library Project, then create an AIR and a Flex project that is simply a shell that brings in the library project. I did this when I was too lazy to make an ant build file that could generate both Flex and AIR from the same project and because it was easier for developers not used to ant to pick up and use in Flex Builder. If I had the time I would make an ant file but separating into a library is quick and easy. best of luck /r http://www.searchcoders.com/ On Wed, May 7, 2008 at 10:18 AM, Geoffrey [EMAIL PROTECTED] wrote: I have an existing Flex app... a pretty complex one.

[flexcoders] Re: Can AIR app get Workstation Credentials?
I've decided to create a login panel to allow the user to login first, but I've run into a snag. We're using acegi as our security layer, and it intercepts all requests checking for state. I thought that I could just call the j_acegi_security_check.jsp directly supplying it with user and password, but it returns the acegilogin.jsp page. I noticed that my initial request to the j_acegi_security_check.jsp page had no jsessionid associated with it, so I thought that was the problem. To test that idea I created another HTTPSession request that gets spit out upon applicationComplete to a bogus page on the server. Now my AIR session seems to have the JSESSIONID cookie set because when I send the real 'logon' request, I see the same JSESSIONID in the header. Unfortunately, this didn't work either because I still get the acegilogin.jsp page returned to me. The only real difference I see between the web and AIR requests is that the 'Referer' is different in the header. From AIR, the referer is app:/AirMain.swf, from the web version of our app it's acegilogin.jsp;jsessionid=098CEB40890309539C7E50EF410B54DE.

[flexcoders] Stress Testing a BlazeDS Application
Is there a FREE way to stress test a real-time messaging BlazeDS application? I tried using JMeter, but I can't capture all of the http request data to set up the test because you need to use a proxy for that, and BlazeDS falls back to a polling channel if a proxy is used. I looked in flexunit, but that doesn't seem like it's appropriate for this type of test. I want to establish 100, 200, 300,... clients until it breaks the server. All that needs to happen is a login(via acegi security) and a Consumer subscription request. Unfortunately, acegi requires a jsessionid for each http request to validate, and that's what I'm having difficulty with. Basically, any requests to the server are interrupted by acegi and the jsessionid is validated. If the validation is successful, the web asset is fetched. If validation fails, the login JSP page is returned. This is also causing issues with an AIR app that I have that has a flex login interface. The jesssionid doesn't seem to get cached within the AIR http request headers. Thanks for any help. ~Geoff~

[flexcoders] RTMP and Spring Security(Acegi) Issues
I'm wondering if anyone out there has implemented LiveCycle Data Services using Spring Security as their security layer? I'm having issues with RTMP communications between server/client, meaning I'm not getting any. I've modified our existing Java delegate to ast as the Assembler for a managed collection. When the Assembler's fill() method gets called, it tries to retrieve the desired information from our Service class. I get an AuthenticationCredentialsNotFoundException as seen below: error snippet org.acegisecurity.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext at org.acegisecurity.intercept.AbstractSecurityInterceptor.credentialsNotFound(AbstractSecurityInterceptor.java:339) at org.acegisecurity.intercept.AbstractSecurityInterceptor.beforeInvocation(AbstractSecurityInterceptor.java:254) at org.acegisecurity.intercept.method.aopalliance.MethodSecurityInterceptor.invoke(MethodSecurityInterceptor.java:63) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:161) at org.springframework.aop.framework.Cglib2AopProxy$DynamicAdvisedInterceptor.intercept(Cglib2AopProxy.java:630) ... /error snippet I think it's because the HTTPFlexSession is authenticated, but the RTMPFlexSession operates outside the context.

[flexcoders] Re: RTMP and Spring Security(Acegi) Issues
I'm guessing that we don't implement security the correct way (or the best way) right now. Currently, I have a login State that takes the username and password and makes an HTTPService call to the JSP page that does user authentication. If that comes back successfully, then I change State to the main application. That seems to take care of all of the HTTP requests, but the RTMP requests obviously fail (or else I wouldn't be here ;-)). I read the docs about using LoginCommand, but I didn't see how that ties into Acegi. I'm wondering if you can authenticate the Flex client, and not just the session.

[flexcoders] Re: RTMP and Spring Security(Acegi) Issues - SOLVED
I seem to have got it working. Thanks for your help jahhaj12345!
What I ended up doing was to create a custom LoginCommand class. I
used the one from here:
http://blog.f4k3.net/fake/entry/acegi_logincommand_for_fds. I made
two changes shown below:
//The name of our Acegi configuration file.
private static String[] CONFIG_LOCATIONS =
{classpath:security-context.xml};
//ldapAuthenticationProvider is from our Acegi config file, and it
the name of the bean that is used for authentication via LDAP.
authenticationProvider =
(AuthenticationProvider)applicationContext.getBean(ldapAuthenticationProvider);
I then updated services-config.xml and added:
security
login-command class=com.gdais.security.AcegiLoginCommand
server=Tomcat/
security-constraint id=basic-read-access
auth-methodBasic/auth-method
roles
roleROLE_MANAGERS/role
roleROLE_USERS/role
/roles
/security-constraint
/security
//The roles came from the Acegi config file.
After that, I had to add the [managed] metadata tag to one of my
ValueObjects and it all seemed to work.
I'll be honest, I don't really understand why this works, it just
does. What I mean by 'works' is that the managed collection on the
client gets filled with data successfully. I haven't yet tested
pushing new entries to that managed collection after the initial fill.
I hope this post helps someone else.

I've read, you have to authenticate the HTTP and RTMP sessions
individually. For my application, I had to create my own LoginCommand
to handle the flex RTMP authentication.
Here's my understanding of how it's working for me:
1. On my client, I get the channelset to use and then call
channelSet.login(username, password). You could also call the
setCredentials on the actual DataService the same way, but my services
are all created at runtime on the server instead of being statically
defined in services-config.xml.
2. That channelSet (or dataservice) from above authenticates through the
login-command configured in services-config.xml. This is where the
custom LoginCommand I created is configured. The doAuthentication
function of LoginCommand is as follows:
public Principal doAuthentication(String username, Object
credentials) {
Authentication auth = authenticationProvider.authenticate(new
UsernamePasswordAuthenticationToken(username, credentials)); //
authenticationProvider is a spring security DaoAuthenticationProvider
SecurityContextHolder.getContext().setAuthentication(auth);
return auth;
}
This should authenticate the RTMP session. I don't know if this is the
best way, but it seems to work.

One last thing I had to do to get it to work. I added
-Dacegi.security.strategy=MODE_INHERITABLETHREADLOCAL to my Tomcat
JVM arguments. Otherwise, setting and getting the Authentication
object was accessing different instances of some security object.

That seems to take care of all of the HTTP requests, but the RTMP
requests obviously fail (or else I wouldn't be here ;-)).
I read the docs about using LoginCommand, but I didn't see how that
ties into Acegi.
I'm wondering if you can authenticate the Flex client, and not just
the session. If so, wouldn't the sessions (HTTP and RTMP) also be
authenticated since they fall under the FlexClient object? Just a
thought.

To get it working without rememberme, provide a login form
from your
flex application and once authenticated using form login, use that
username/password combination for the RTMP's ChannelSet login.
And
depending on how you handle authentication on your end, you
may need
to provide your own LoginCommand and UserDetailsService. I've

both of these and it works.
Does anyone out there have a way to get rememberme working for

[flexcoders] LCDS Memory Usage
Looking in the LiveCycle Data Services ES Developer's Guide, page 190, it states: By default, the Data Management Service caches items returned from fill() and getItem() calls and uses cached items to implement paging and to build object graphs on the server when implementing lazy associations. This causes a complete copy of the managed state of all active clients to be kept in each server's memory. Here's what I think that means. If I have 100 clients, and each client has one managed collection that contains 100 items in it, then there would be 10,000 copies residing in memory on the server(100 objects for 100 users). Am I understanding this correctly? Does this seem inefficient? What if those objects happened to be really big objects... I mean really big. Seems like that would take up a lot of memory on the server. Has anyone come up against this in practice? Thanks, Geoff
[flexcoders] Re: LCDS Memory Usage
I saw that you can turn cache-items to false and it will only store the IDs in memory, but at the expense of paging, or at least more efficient paging. Is this true? I thought the docs said that to do paging it would have to grab all the objects again, then grab the subset of data you want. In our particular instance, we have very large objects that are relatively unique across clients. Some objects will be shared, but most won't. Just trying to forecast how it will effect the server. Thanks, Geoff --- In flexcoders@yahoogroups.com, Jeff Vroom [EMAIL PROTECTED] wrote: That is basically how it works but only if you have auto-sync enabled=true and cache-items=true on your destination settings. The auto-sync feature requires that we maintain at least the identities of all objects managed on every client so that we know where to push changes. The goal here is that you don't have to worry about tracking that and can still easily keep clients in sync. Also, if two clients fetch an object with the same id, only one copy is cached. If you turn cache-items=false, we cache only the ids, not the items so we keep a lot less state around (though we do have to go back to the assembler more often so that is more load on the database). If you turn auto-sync off, the server maintains no state but the synchronization functionality would then only work if you enable manual sync - i.e. where your clients specify subscriptions they want to listen to and also can specify meta-data that is attached to all changes made. That meta-data is used to route changes to the right subscribed clients.

[flexcoders] LCDS - Tomcat - JOTM Integration
After a couple days of fussing around, I was able to successfully
integrate JOTM into our webapp, and thought that I'd share what I did.
Hopefully it will be useful to someone else.
Environment:
Eclipse 3.3.1.1
Tomcat 6.0.16
LCDS 2.5.1
JOTM 2.0.10
Installation:
1) Download JOTM 2.0.10 from http://forge.objectweb.org/projects/jotm/
if you don't already have it.
2) Unzip to c:\
3) Link those jars to Tomcat
a. Double-click Tomcat definition in the Servers tab of Eclipse.
b. Click Open launch configuration.
c. Select the Classpath tab.
d. Select User Entries, and then Add External JARs.
e. Navigate to C:\jotm-2.0.10\lib.
f. Select all classes except commons-logging.jar and log4j.jar.
g. Apply the changes and exit Tomcat properties.
h. (optional) test JOTM installation by starting the server and
accessing the below JSP file*. Success will be obvious.
4) Edit your META-INF\context.xml to include the following line:
Transaction name=UserTransaction auth=Container
factory=org.objectweb.jotm.UserTransactionFactory jotm.timeout=60/
You should now be able to perform create, delete, and update
operations on a managed collection of a DataService.
* Optional JSP file(I got this from someone in this forum, but can't
remember who)

[flexcoders] How do you auto-refresh LCDS?
I'm not sure how you refresh clients when there's a change on the
server. After I perform a _ds.fill(), the user can delete 1+ of the
items from the managed collection. The ActionScript looks like:
private function deleteItems():void
{
var selectedTasks:Array = taskList.getSelectedTasks();
for each (var task:ExploitationTaskVO in selectedTasks)
{
_ds.deleteItem(task);
}
// Commit the deletes to the server if needed
if (__ds.commitRequired)
{
__ds.commit();
}
}
_ds.commit() has to be called to propagate changes to the server
because I have _ds.autoCommit = false.
The LCDS JavaDocs state that changes from a createItem() or
updateItem() call will propigate to all clients if auto-refresh=true.
Is that true for deleteItem() calls too? And where is this
auto-refresh property? I don't see it under Java AbstractAssembler or
ActionScript DataService classes.
Also, what if I create, update, or delete a task on the server without
doing it through the DataService(like through a java delegate). Can I
force the DataService to refresh it's clients on the java side? Is
this what the DataServiceTransaction.refreshFill() method is for?
Thanks,

It could be the case that for some reason the fill parameters are not matching the fill parameters used by your clients or that when FDMS calls the fill method on the assembler, it sees the same item ids returned that are already on the client. Turning on the server debug logging for the pattern DataService.* (in 2.0.1) and Service.Data.* (in 2.5) would provide more diagnostics about what is happening. One other problem with refreshFill is that if the properties of the items have changed but the identities of the items in the filled collection have not, the refreshFill won't pick it up. RefreshFill is just about refreshing the membership of the objects in the filled collection - i.e. which items are in that list. It is not about updating the properties of the items in the filled collection. To update those properties, you need to call dts.updateItem for each item where the properties have changed. If bandwidth/performance is not too much of a problem, you can simply call updateItem for each item id in the list where you just pass in null for the previous item and null for the list of properties that have changed. This is similar in performance to just having the clients re-execute the fill since they will be pushed all of the items in the collection and will update their local copies of all of the items with these changes. Part of the rationale for this behavior is that we don't want to necessarily cache a copy of every managed item on the server. That is really the only way we can know whether an item has changed (by comparing the old and new versions) and is somewhat expensive. That said, if you do have the cache-items setting turned on, we should be able to do a better job of this even if it takes a few CPU cycles. I think we already have an enhancement filed for this feature but I'll check and if not file one.

//ldapAuthenticationProvider is from our Acegi config file, and it
the name of the bean that is used for authentication via LDAP.
authenticationProvider =

security
login-command class=com.gdais.security.AcegiLoginCommand
server=Tomcat/
security-constraint id=basic-read-access
auth-methodBasic/auth-method
roles
roleROLE_MANAGERS/role

//The roles came from the Acegi config file.
After that, I had to add the [managed] metadata tag to one of my
ValueObjects and it all seemed to work.
I'll be honest, I don't really understand why this works, it just
does. What I mean by 'works' is that the managed collection on the

pushing new entries to that managed collection after the initial fill.

channelSet.login(username, password). You could also call the
setCredentials on the actual DataService the same way, but my
services
are all created at runtime on the server instead of being statically
defined in services-config.xml.
2. That channelSet (or dataservice) from above authenticates
through the
login-command configured in services-config.xml. This is where the
custom LoginCommand I created is configured. The doAuthentication
function of LoginCommand is as follows:
public Principal doAuthentication(String username, Object
credentials) {
Authentication auth =
authenticationProvider.authenticate(new
UsernamePasswordAuthenticationToken(username, credentials)); //
authenticationProvider is a spring security
DaoAuthenticationProvider
SecurityContextHolder.getContext().setAuthentication(auth);
return auth;
}
This should authenticate the RTMP session. I don't know if this
is the
best way, but it seems to work.

that does user authentication. If that comes back successfully,
then
I change State to the main application.
That seems to take care of all of the HTTP requests, but the RTMP
requests obviously fail (or else I wouldn't be here ;-)).
I read the docs about using LoginCommand, but I didn't see how
that
ties into Acegi.
I'm wondering if you can authenticate the Flex client, and not
just
the session. If so, wouldn't the sessions (HTTP and RTMP) also be
authenticated since they fall under the FlexClient object? Just a
thought.

[flexcoders] LCDS: Debug RTMP Traffic
I'm having some issues with 2 DataServices running over RTMP. The first DataService loads on application startup and work fine (I get data). The second load later on in the application, but this one get's no data. It doesn't appear that it even makes the connect request because my result and fault handlers don't get hit. Is there a tool (like Charles, ServiceCapture, or Wireshark) that can be used to verify that something over an RTMP channel is being sent from the client? Like I said, nothing seems to happen when I issue the DataService.connect() call. I've enabled a bunch of logging on the server(via the services-config.xml file), but if that traffic isn't reaching the server, all the logging in the world won't help. BTW, if you say that Wireshark can be used, then please post the filter you use because I couldn't figure out one that only showed RTMP traffic. As a matter of fact, I couldn't find anything that looked like RTMP traffic in the log session. I don't know if it's important or not, but the server and the client are all running locally.

[flexcoders] Re: LCDS: Debug RTMP Traffic
Our endpoints are created in the services-config.xml, and the destinations for DataServices are configured in data-management-config.xml. the RTMP endpoint config is as such: channel-definition id=my-rtmp class=mx.messaging.channels.RTMPChannel endpoint url=rtmp://localhost:2039 class=flex.messaging.endpoints.RTMPEndpoint/ properties idle-timeout-minutes30/idle-timeout-minutes /properties /channel-definition A DataService destination looks like: default-channels channel ref=my-rtmp/ /default-channels destination id=tasks adapter ref=java-adapter / properties use-transactionstrue/use-transactions sourceblah.blah.blah.TasksDelegate/source scopeapplication/scope cache-itemsfalse/cache-items metadata identity property=id/ /metadata network subscription-timeout-minutes0/subscription-timeout-minutes paging enabled=false/ /network /properties /destination The two destinations are identical, except for the source class. I am using the compiler argument [-services C:\workspace\flex\src\main\webapp\WEB-INF\flex\services-config.xml], which points to the correct services-config.xml file. The task DataService is created in ActionScript like so: // Create a datasource __ds = new DataService(tasks); __ds.cacheID = ExpTasks; __ds.autoSaveCache = false; __ds.autoConnect = false; __ds.autoCommit = false; __ds.addEventListener(DataConflictEvent.CONFLICT, onDataConflict, false, 0, true); __ds.addEventListener(DataServiceFaultEvent.FAULT, onDataServiceFault, false, 0, true); // Connect to datasource connect(); The connect() method just registers some event listeners and then calls __ds.connect(). The whole point to this is that we intend to replace our 30 Java delegates and 130+ remote methods with DataServices so our application can run in offline mode (assuming there's cached data). If there's a better way to do this, I'm open to suggestions.

How is its channelSet specified - on the client via the channelSet property or on the server?

[flexcoders] Resource Bundle Missing in AIR
I'm using localization on a flex project for a slightly different use. We have 2 projects that share the same code base, but we want to change some UI text that's displayed. So, we're using localization to swap certain text strings to be project specific. Everything works fine for the web version, but if I try to take that same localization setup and use it in our AIR version, it cannot find the required resource bundles. I've looked and they(web/AIR) appear to be set up identically. My locales are: en_US_ProjA and en_US_ProjB. The AIR compiler argument is -locale=en_US,en_US_ProjA. I only put the one project in to test getting the proper resource. My directories are: projRoot.src.locale.en_US.* projRoot.src.locale.en_US_ProjA.* projRoot.src.locale.en_US_ProjB.* When I debug a piece of localization code I see that the localeMap has 2 entries, en_US and en_US_ProjA. Both contain the same entries, but the properties files are pointing to different Obects. For example: en_US_ProjA$CairngormMessages_properties (@c3547b9). I should be seeing a UI_Text property file in the list of resource bundle objects, but it's missing. I'm stumped as to why it works just fine from a browser, but pukes in AIR. Thanks, Geoff

[flexcoders] LCDS: DataService.fill() not filling
Does anyone know what would prevent a DataService.fill() call to not populate it's managed collection? I have an ArrayCollection that is the dataProvider for a DataGrid. I see that data is coming back from the fill() call, but it doesn't appear to be passing that data to the ArrayCollection. If I inspect that variable after the fill() completes, it's empty. I double checked that the ArrayCollection that I'm passing to the fill() method is indeed the one that is used as the dataProvider. Any thoughts would be appreciated. ~Geoff
