[flexcoders] Hide a list item without changing (filtering) the dataprovider?
Hallo!
How can i hide a list item. I am trying to make a lists and hide the
'mandatory=true' items without changing (filtering) the dataprovider.
As far as i know i can even make a deep copy of the dataprovider and
set a filter on it, but i'd like to prevent this. The code below hides
the items, but they still fill the height in the list.
Thanks in advance!

[flexcoders] Cannot access a property or method of a null object reference at mx.controls::Tree/::buildUpCollectionEvents()
Hi All!
When I add a new item to the tree node and then open this item by user input
null pointer exceptions is thrown and after that Tree behavior becomes
strange.
Steps to reproduce:
1. Run application.
2. Select My Branch node.
3. Click Add button. As a result My Leaf subnode is created as a child of My
Branch.
4. Click My Leaf disclosure icon to expland this item.
5. Exception mentioned above is thrown.
I compile this example in Flex 2.01 and run in Flash Player 9.0.47.0.
We have found workaround. The bug can be fixed by setting Tree
openDuration style to 0. But I dislike workarounds. Are there any real
solutions to fix this bug?
Sergey.

You don't have to do a deep copy. Use ListCollectionView instead, which allows you to apply different filters to the same underlying Collection. Cheers Ralf.

[flexcoders] Re: Sorting behaviour of AdvanceDataGridControl
I don't have any suggestions, but we have this problem too. In fact if you have a list of items sorted according to a specific column, and change a property of an item in the collection unrelated to the sorting; it often reorders items in the collection if their sorting properties are equal. To the user this behaviour seems very erratic. Afaik. this behaviour is somewhere in ArrayCollection (or its supertypes) and not in the AdvancedDataGrid. --- In flexcoders@yahoogroups.com, mishrabagish [EMAIL PROTECTED] wrote: I have a ADC in my application .

[flexcoders] Re: Draw colored shape
Yes, it will show row background, but, .. no column background
anymore. So, it's the same as not to have column background in the
first place. But what I want is to have columns with backgrounds and
then color some rows keeping columns unchanged. Is that possible in
Flex?
--- In flexcoders@yahoogroups.com, Enjoy Jake [EMAIL PROTECTED] wrote:
You're right. Your column backgroundColors are being displayed on
top of your row background Colors. The fact is, you have to choose
one or the other to be on top. Adobe decided that column colors
should always be displayed over row colors. If you want to display
rowColors over column colors, the easiest way to do it is by
overriding updateDisplayList on your datagrid thus:
override protected function updateDisplayList
(unscaledWidth:Number, unscaledHeight:Number):void {
super.updateDisplayList(unscaledWidth, unscaledHeight);
var rowBGIndex:int = listContent.getChildIndex
(listContent.getChildByName(rowBGs));
var colBGIndex:int = listContent.getChildIndex
(listContent.getChildByName(colBGs));
if (colBGIndex rowBGIndex) {
listContent.swapChildrenAt(rowBGIndex, colBGIndex);
}
}
This is starting to get into the realm of ugly hack, so beware.
Much further into that realm is the modified example below. What I've
done is given each item in the dataprovider a default color of
0x. When drawing a row, if the calculated color is 0x
then I do not draw the row, and let the column color shine through.
As I said before, this is getting dangerously ugly, and for the
benefit of the community, further examples of this should probably be
hidden from public view.
Also, beware of retinal damage that could be caused by my awful
choice of colors in the examples.

[flexcoders] blazeds spring security let assembler fetch data based on current user
Hi, I'm currently learning flex by trying to build an application with flex, blazeds and Spring. My application lets users log on using spring security (which I will probably combine with AcegiLogonCommand). I would like my assemblers to return different data based on which user is currently logged on (for instance to show that specific user's to-do list). To do this, I added a userId property to my spring security principals (by subclassing org.springframework.security.userdetails.User) and added user_id columns to user-specific data in the database. Now I would like to know how I can get the currently logged on user in my assembler so I can use its userId to fetch the user's data. Is the assembler the right place to decide which data to send to my flex application? If so, can anyone tell me how to determine which user is currently logged on in my assembler? If not, what would be the recommended way of dealing with user-specific data in my database in combination with blazeds? The only examples I have been able to find on the Internet so far only use different roles to determine what a user is or is not allowed to do, I have yet to find any examples where users store and retrieve user-specific data. Kind regards, Jeroen

[flexcoders] How to load an image using mx:Loader
Hello folks, I'm a newbie in flex-world! I need to load a Bitmap (.jpg) file using Flex3. Now I've read a bunch of code that describes how to do this using ActionScript 3. But I'm not very sure how Flex 3 and AS3 interact. I've got the Flex 3 Builder Eclipse Plugin and I was hoping I could find an example of loading an image using the mx:Loader tag. But strangely I do not see many posts on this forum for this. Could it be that this is the wrong way to load an image using Flex? So, specifically, can someone: 1. Provide me with an example of using mx:Loader to load a .jpg file. 2. Show me a simple example of how Flex3 tags and AS3 interact. For example, if I wanted to build all UI components using Flex, but do all Image manipulation using AS3. Thanks in advance! Pankaj

[flexcoders] Re: Best Practice Data Binding
Thanks very much for your time in writing this; it's very helpful. But
my question still stands: if there are parts of your answer that I
don't understand fully, or that raise more questions in my mind (and
both of these are in fact the case), how do I resolve these
difficulties? How did you learn about this (aside from the LiveDocs,
I mean)? The implementation must be defined *somewhere*, surely, even
if only in code?
--- In flexcoders@yahoogroups.com, Josh McDonald [EMAIL PROTECTED] wrote:
The authoritive story is pretty much as Daniel said:
[Bindable]
public var myField:String;
The above will generate something the equivalent of:
mx_internal var _myField:String; //Might be private, can't be arsed
to check
[Bindable event=propertyChangeEvent]
public function get myField():String {
return _myField;
}
public function set myField(value:String):void {
if (value != _myField) {
var oldVal:* = _myfield;
_myField = value;
dispatchEvent(new PropertyChangeEvent(this, myField, oldVal,
newVal));
}
}
And if you put the generic [Bindable] on a getter _or_ a setter, you'll
re-generate the above code, but _myField will be the original get/set
functions renamed, not a private or mx_internal var.
As a rule, I don't use the generic [Bindable] on getter/setter
functions.
It's just not that hard to dispatch an event.
However if you're going to put generic [Bindable] on a getter/setter
pair,
put it on the *setter*. Otherwise the debugger will hilight the getter
method when you're single-stepping through foo.myField = someValue
- it's
not a law or anything, but it's confusing even when you know why it
does it.
When you're using a custom event, put the
[Bindable(event=myEventName)] on
the *getter*. That way you always know it's bindable, as not every
getter
needs a setter. You can dispatch the event from anywhere you please,
either
a setter method or something else. Don't know about performance, but
when
you're not using a PropertyChangeEvent, bindings will fire for anything
matching that name, since it can't use the fieldName and object
properties
of PropertyChangeEvent to know exactly which field should re-fire
bindings.
One last thing, you can specify
[Bindable(event=PropertyChangeEvent)] on a
getter, and you'll still need to dispatch your own
PropertyChangeEvents from
the setter or from anywhere else. It lets you be a specific as to what's
changed in the object without having a bunch of custom named events.
Disclaimer: I'm 99% sure that's all correct. YMMV ;-)

[flexcoders] Re: Cannot access a property or method of a null object reference at mx.controls::Tree/::buildUpCollectionEvents()
I don't use Flex 2.0.1 (I use Flex 3).
I ran your app in Flex 3 and it works fine - ie. no exception is thrown.
Could this be a bug in Flex 2.0.1?

Hi All!
When I add a new item to the tree node and then open this item by
user input
null pointer exceptions is thrown and after that Tree behavior becomes
strange.
Steps to reproduce:
1. Run application.
2. Select My Branch node.
3. Click Add button. As a result My Leaf subnode is created as a
child of My
Branch.
4. Click My Leaf disclosure icon to expland this item.
5. Exception mentioned above is thrown.
I compile this example in Flex 2.01 and run in Flash Player 9.0.47.0.
We have found workaround. The bug can be fixed by setting Tree
openDuration style to 0. But I dislike workarounds. Are there any real
solutions to fix this bug?

RE: [flexcoders] Re: Best Practice Data Binding
When working in mxml you can use the -keep-generated-actionscript compiler
option. and in the 'generated' directory you will find a wealth of
information!
In short - the answer you seek is before you! Finding the 'solution' is
another story.

Thanks very much for your time in writing this; it's very helpful. But
my question still stands: if there are parts of your answer that I
don't understand fully, or that raise more questions in my mind (and
both of these are in fact the case), how do I resolve these
difficulties? How did you learn about this (aside from the LiveDocs,
I mean)? The implementation must be defined *somewhere*, surely, even
if only in code?

The authoritive story is pretty much as Daniel said:
[Bindable]
public var myField:String;
The above will generate something the equivalent of:
mx_internal var _myField:String; //Might be private, can't be arsed
to check
[Bindable event=propertyChangeEvent]
public function get myField():String {
return _myField;
}
public function set myField(value:String):void {
if (value != _myField) {
var oldVal:* = _myfield;
_myField = value;
dispatchEvent(new PropertyChangeEvent(this, myField, oldVal,
newVal));
}
}
And if you put the generic [Bindable] on a getter _or_ a setter, you'll
re-generate the above code, but _myField will be the original get/set
functions renamed, not a private or mx_internal var.
As a rule, I don't use the generic [Bindable] on getter/setter
functions.
It's just not that hard to dispatch an event.
However if you're going to put generic [Bindable] on a getter/setter
pair,
put it on the *setter*. Otherwise the debugger will hilight the getter
method when you're single-stepping through foo.myField = someValue
- it's
not a law or anything, but it's confusing even when you know why it
does it.
When you're using a custom event, put the
[Bindable(event=myEventName)] on
the *getter*. That way you always know it's bindable, as not every
getter
needs a setter. You can dispatch the event from anywhere you please,
either
a setter method or something else. Don't know about performance, but
when
you're not using a PropertyChangeEvent, bindings will fire for anything
matching that name, since it can't use the fieldName and object
properties
of PropertyChangeEvent to know exactly which field should re-fire
bindings.
One last thing, you can specify
[Bindable(event=PropertyChangeEvent)] on a
getter, and you'll still need to dispatch your own
PropertyChangeEvents from
the setter or from anywhere else. It lets you be a specific as to what's
changed in the object without having a bunch of custom named events.
Disclaimer: I'm 99% sure that's all correct. YMMV ;-)

[flexcoders] RadioButtons appear as normal buttons -- WTF?
This is driving me nuts. I'm using two RadioButtons in a RadioButtonGroup, and they appear as two normal buttons. There is no CSS styling in effect. I'm not setting any properties other than label, group and labelPlacement and selected. Does anyone know what is going on here?
Re: [flexcoders] CurrencyFormat vs locale
Thanks, I'll look at that. Gordon, it's just a case that the app as a whole is not being localized for everywhere just yet.

[flexcoders] Cancelling a checkbox.selected
Hi Everybody,
I have an options button which leads to a new sate options_state
when it is clicked.
In this new state, I have a checkbox and two buttons cancel and valid.
I handle fine the valid button which gets the checkbox state and
save it,
to display it again when the application is relaunched.
Now my problem is if I change my checkbox state, then change my mind,
I can do cancel, but
I don't see how anymore after tried several ways of doin' it...
Sorry for sounding kind of basic... :-(
With a little help from my friends...
Thx for the Light !
here is the snippet of code:
private function onOptions():void
{
this.currentState = options_state;
setOptions();
}
// to handle the prefs when app is launched
private function setOptions():void
{
if ( Flags.flag_startAtLogin == 0 )
{
checkbox_options.selected = true;
}
checkbox_options.addEventListener( Event.CHANGE, checkOptions );
}
private function checkOptions( evt:Event ):void
{
if ( checkbox_options.selected == false )
{
flag.setFlag( 1 );
checkbox_options.selected = false;
//NativeApplication.nativeApplication.startAtLogin = false;
} else
{
flag.setFlag( 0 );
//NativeApplication.nativeApplication.startAtLogin = true;
}
}
private function onValider():void
{
savePreferences.createXMLData();
savePreferences.writeXMLData();
this.currentState = ;
}
private function onAnnuler():void
{
this.currentState = ;
}
[flexcoders] Still having issues with quitting AIR app from ApplicationMenu and DockMenu
I gave up on this temporarily and decided to revisit this morning. Around the time the AIR 1.1 update came out, I started having issues quitting the AIR app I'm developing using Apple-Q, the ApplicaitonMenu, and the DockMenu. It seems to be related to the fact that I have other windows opened by my application, the only way I can currently quit the entire application is by closing my Main window, which my windowedApplication listens to and then closes. I've even tried adding a listener to the Quit item in the ApplicationMenu, but my handler is never catching the event when I choose that item. Other AIR apps I have installed are still working correctly, so I'm looking for the culprit here. My application extends WindowedApplication, it is chromeless, transparent, and invisible. It spawns a MainWindow on startup, but other windows for notifications, etc, are also spawned from the application. I listen for the CLOSING event on the MainWindow and then close the application, which works fine. Mac users are just used to Apple-Q to quit and this is doing nothing currently.
[flexcoders] Full Screen and Scaling in FLEX. Please help
Hi Flexcoders
I have a question. I made an application and I like to give user the
option of clicking on full screen. I implemented the following code
and full screen is working fine. When user clicks on Full screen the
whole application takes place of the monitor but my problem is that
the application does not scale, so it looks weird. Please help me out,
I need full screen scaling of my whole application. However I
implemented same thing in AS 3.0 uisng Flash IDE just by using
addEventListener(Event.ENTER_FRAME,setStage);
function setStage(event:Event):void
{
stage.displayState = StageDisplayState.FULL_SCREEN;
fscommand(fullscreen, true);
fscommand(allowscale, true);
}.
But this techniques is not working in Flex. I am trying to run
independent SWF file for full screen, With Browser definitely this
thing is not going to work but i need full screen in SWF file.
Please help
Thanks

[flexcoders] Re: Cancelling a checkbox.selected
Hi,
to display it again when the application is relaunched
This implies that you are saving and loading the pref settings data. If
the user clicks the cancel button, you could reload the settings data
that is already saved. For CRUD, it sometimes makes sense to edit a
copy of the persisted data. That way, if the user cancels, just blow
away the copy. If they save, send the edited copy to the server and
update the model with the returned object; or directly from the copy, if
you're not worried about sync issues and want faster user feedback.

Re: [flexcoders] CurrencyFormat vs locale
You may be right, but let me give you a little more context. The English application (or a future non-English version) can display monetary values in a currency determined by a server setting. The English application might be used in other countries before a localized version is available. It would be nice, though perhaps not essential, for currencies to be displayed with locale-sensitive separators. I'm not sure about SharedResources, but I supposed I could have a currency.properties file and create locale folders for each locale that only contain the currency properties, defaulting to the en_US separators for locales that are not yet added to the build. Thus the application would be localized but only with respect to currency (and perhaps date formats). Any reluctance to add multiple locales now, is largely a question of timing/app size/impact on build system. Somewhat tangentially, will there be better tooling support for localization in Flex 4?

Re: [flexcoders] override updateDisplayList
Perhaps the fix is obvious, but if not just add a couple null checks. After
all, if colBGs is null, then it's certainly not going to be displayed in
front of rowBGs so there's no need to swap them. Something like this should
do fine:
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void {
super.updateDisplayList(unscaledWidth, unscaledHeight);
var rowBGs:DisplayObject = listContent.getChildByName(rowBGs);
var colBGs:DisplayObject = listContent.getChildByName(colBGs);
if (rowBGs != null colBGs != null) {
var rowBGIndex:int = listContent.getChildIndex(rowBGs);
var colBGIndex:int = listContent.getChildIndex(colBGs);
if (colBGIndex rowBGIndex) {
listContent.swapChildrenAt(rowBGIndex, colBGIndex);

Re: [flexcoders] How to load an image using mx:Loader
I'm not sure how much you know about Flex or Actionscript, so i
decided to just give some example code:
!--THIS IS THE IMAGE PORTION--
mx:Image id=myImage source=pic.jpg/
!--AND THIS IS THE ACTIONSCRIPT EMBEDED IN THE MXML--
mx:Script
![CDATA[
private var desiredWidth:int = 300
private function changeWidth():void
{
myImage.width = desiredWidth
}
]]
/mx:Script
In the first portion the image is defined in the mxml, note I defined
and id property as well as source. I then use the id again in the
actionscript. I used it in a function so a button could trigger that
function and change the width of the image to 'desiredWidth' variable
at runtime.
I hope this helps

[flexcoders] Re: THIS IS ABSOLUTELY NUTS
Dan, I've often found that I need to delete the old file(s) before uploading the new file to the net. This is either to do with the FTP software and/or the hosting company. If you don't delete it first, sometimes it doesn't overwrite the old file, and it seems some hosting companies have a cache of some type on their servers, and it takes a while for your new file to be what is displayed when browsing to your site. I've seen it take over 1 hour before the new file gets displayed. Deleting the file, however, seems to force it to recognize the new file.

[flexcoders] Strange problem with Flex-Builder
Hi All, i found a strange behavior in Flex-Builder (plugin) on OSX 10.4.11 when using the Go to Definition or hyperlink navigation feature. When I open a file from flex navigator the file opens in the editor. When I then put the cursor on a variable that has its definition in the same file and I choose Go to Definition from the context menu or press F3, the same file opens in a second tab in eclipse and the definition of my variable is highlighted. When I close this second tab, Go to definition won't work anymore until I close the file and reopen it. The strange thing is, that when I keep the second tab open and close the first, Flex Builder now exactly does what I want: Go to the definition of the variable in the same tab. Does anybody have the same problem or is there a solution for this issue? Thanks in advance, John
[flexcoders] Problem with selectedIndex on dynamically populated combobox (Cairngorm)
Hello all,
I've stumbled across an issue when building an application using
Cairngorm that I hope someone can help with.
The relevant part of the application is a component wrapping a
datagrid with paging/search controls. I am having an issue
specifically with the 'jump to page' combobox.
I'm using databinding to assign the dataProvider for the combobox from
a public property on my Cairngorm ModelLocator but the problem is that
while the options for the combobox are getting populated correctly,
the selectedIndex (bound to another property of my ModelLocator) isn't
getting set.
My combobox code:
mx:ComboBox id=pageMenu_cb
dataProvider={getPageMenuOptions(this.recordSetVO)}
change=onPageMenuChange();
selectedIndex={getPageMenuIndex(this.recordSetVO)}
enabled={getPageMenuEnabled(this.recordSetVO)} /
* recordSetVO is a reference to the ModelLocator property.
The functions used in the databinding individually all return what's
expected. I suspect that in databinding both the dataProvider AND the
selectedIndex Flex is tripping up somehow. Maybe there's another way
to achieve what I need - the current page to show as selected based on
the data returned (with a list of page numbers populating the combobox).
Has anyone else encountered such a problem and/or can recommend a fix ?
Thanks in advance.

[flexcoders] Sizing Components Inside Custom UIComponents
I'm pretty new to Flex. I've created some custom components by extending UIComponent. I've implemented createChildren, commitProperties, measure, and updateDisplayList. I can resize the custom UIComponents using any number of methods: constraints, CSS, etc. They resize no problem. But if I try to size a child of that custom component, no width or height is assigned, unless I use an explicit setActualSize. For example: My custom component (Content) has been added to a canvas. The component is sized using width and height properties: var content:Content = new Content; content.width = 800; content.height = 800; addChild(content); In content, in createChildren, I create an instance of the Image component. var container:Image = new Image; container.scaleContent = false; addChild(container); I try to do this: container.percentWidth = 100; container.percentHeight = 100; But nothing. I can only seem to resize this inside updateDisplayList like so: container.setActualSize(unscaledWidth, unscaledHeight); Thanks, Brandon

[flexcoders] Flex app only works on Windows?
Hi all, I built a Flex app which works fine on Windows machines, but on Macs and Linux it won't load. It shows the little loading box with the progress bar, then just goes to a blank screen. I originally thought there was some issue with the html wrapper or maybe the javascript but even when going directly to the .swf file, I see the exact same behaviour.

[flexcoders] Issues panning a swf loaded via SWFLoader
I'm loading a swf into a SWFLoader (earth-shattering, I know). The swf document size itself is set 2800x960, but there is an additional element beneath this in the pasteboard (what was the flash 8 workarea) that is about 500px in length. I need to be able to pan down to this element. If make a call to set the y value of the SWFLoader to -500 (to pan downward) the area above it hovers above my flex components instead of going underneath. I went a step further and wrapped the swfLoader in a Canvas object. Setting the y value to -500 on the MXML object did just what I wanted to. I then began setting this dynamically, which produces the same results as before. I also tried to run validateDisplayList() hoping it would fix things but to no avail. Any suggestions would be greatly appreciated :)
[flexcoders] Flex Builder Eclipse Builder Syntax Checking
Greetings all! This is my first post up here, as I've been able to solve all of my previous problems by searching, but I've spent the last 7 hours banging my head against a wall and can't find any help anywhere. Here's the issue: I'm working on a Postgres/Java Servlet/Flex web app using Eclipse 3.3.2 and the Flex Builder 3.0.1... Plugin. Worked fine until yesterday, when Eclipse stopped recognizing errors in my Flex and Actionscript syntax. Missing semicolons, arbitrary gibberish, and a myriad of other errors slide right by and don't show up until I run my ant build and it crashes. Syntax checking still works fine in all of my Java code, so it seems to be localized in the Flex Builder. I found one or two other posts in my searches (not in flexcoders, but elsewhere) with no response or solution. I tried downloading a fresh eclipse 3.3.2 zip and unpacking it to a new directory and installing Flex builder fresh, to no avail. All of the filters for the Problems are clear and it is set to check for Flex errors, as well as Build Automatically. The fresh install had no other plugins, so there shouldn't be any conflict issues. I also haven't made any changes to my configuration (as far as I can remember. there must be something to cause such a mess). If anyone has any advice please let me know, I'm willing to try anything at this point. Thank You! Steve Baney
[flexcoders] updating the Flex tree without reassigning the data provider
Hi, I am trying to build a web based JMX monitoring and management console using adobe FLEX on the client side. This is similar to the flex admin that comes with the LiveCycle installation.I have put snapshots of both flex admin and my tool in the link below. http://picasaweb.google.com/goutham.pulluri/FlexPics In these pictures you would see that there is a tree control in both applications. Now the data provider for the tree control in my application is an XML(see below) assigned using the HttpService. Now everytime something changes on the MBeanserver I want to update the tree. But simply reassigning the data provider would cause the tree to collapse. Is there a way I could dynamically update the nodes without reassiging the data provider? Please let me know any solution you might think of. I was thinking that I may have to write my own control instead of using the tree control .. i dont know how to do it though. Any inputs are welcome. Also if anyone knows how the flex-admin is actually implemented please share that info with me *** Thanks in advance Goutham ?xml version=1.0 encoding=UTF-8? centralmbeanserver element label = FMC-DropCopies-QA canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA element label = Cache Manager canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager element label = SACFixFilterRulesCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACFixFilterRulesCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 68*DBPoolName = FMCDBPoolSACTrades*DBStatementName = GetSACFixFilterRules*Keys = [ExecTransType, OrdStatus]*RowCount = 34 /element element label = SACFIXExecBrokerMapCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACFIXExecBrokerMapCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 1562*DBPoolName = FMCDBPoolSACTrades*DBStatementName = GetSACFIXExecBrokerMap*Keys = [TradeSource, TSExecBroker]*RowCount = 781 /element element label = SACFixIssueMapCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACFixIssueMapCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 8506*DBPoolName = FMCDBPoolSACTrades*DBStatementName = GetSACFixIssueMap*Keys = [SourceIssueID]*RowCount = 8506 /element element label = SACFIXNEOVAcctFilterCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACFIXNEOVAcctFilterCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 1*DBPoolName = FMCDBPoolSACFixFeed*DBStatementName = GetSACFIXNEOVAcctFilterCache*Keys = [Account]*RowCount = 1 /element element label = SACFixFutureDetailsCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACFixFutureDetailsCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 8498*DBPoolName = FMCDBPoolSACTrades*DBStatementName = GetSACFixFutureDetails*Keys = [SourceIssueID]*RowCount = 8498 /element element label = SACAccountDetailCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACAccountDetailCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 236184*DBPoolName = FMCDBPoolSACTrades*DBStatementName = GetSACAccountDetail*Keys = [TradeSource, Account]*RowCount = 118092 /element element label = SACCommRateDefaultMapCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACCommRateDefaultMapCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 944*DBPoolName = FMCDBPoolSACTrades*DBStatementName = GetSACCommRateDefaultMap*Keys = [Broker, CommType]*RowCount = 472 /element element label = SACIssueCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACIssueCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 66568*DBPoolName = FMCDBPoolInterfaces*DBStatementName = GetSACIssue*Keys = [IssueID]*RowCount = 66568 /element element label = SACFMCConfigCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACFMCConfigCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 196*DBPoolName = FMCDBPoolSACFixFeedDev*DBStatementName = GetSACFMCConfig*Keys = [SenderCompID, TargetCompID]*RowCount = 98 /element element label = SACFixTradeSourceConfigCache canonicalName = CentralMBeanServer:App=FMC-DropCopies-QA,Componet=Cache Manager,DB Cache=SACFixTradeSourceConfigCache operations = reloadDBCache:java.lang.String attributes = ValueCount = 704*DBPoolName = FMCDBPoolSACTrades*DBStatementName = GetSACFixTradeSourceConfig*Keys = [TradeSource]*RowCount = 704 /element element label = FUTCommRateDefaultMapCache canonicalName =

I need to load a Bitmap (.jpg) file using Flex3.
Now I've read a bunch of code that describes how to do this using
ActionScript 3. But I'm not very sure how Flex 3 and AS3 interact.
I've got the Flex 3 Builder Eclipse Plugin and I was hoping I could

2. Show me a simple example of how Flex3 tags and AS3 interact. For

RE: [flexcoders] blazeds spring security let assembler fetch data based on current user
You can store user-specific data in the server-side FlexSession or FlexClient instances that you can access via the FlexContext class. A FlexSession represents the connection between a client and server, and in the case of servlet-based HTTP, wraps the app server's HttpSession. One thing that can trip people up is that a cookie-based browser session is scoped to the browser process, meaning all tabs/frames/etc. share the same session. The FlexClient instance on the server represents a specific Flex application (a swf). Both provide APIs for storing and getting attributes and you can access them from within your assembler. Login commands return a Principal as a result of successful authentication, and this is stored in either the FlexSession or FlexClient depending on how you want to scope your authentication. The default is to store it with the FlexSession, but this can be controlled using the per-client-authentication/ config setting for your login command in services-config.xml.

My application lets users log on using spring security (which I will probably combine with AcegiLogonCommand). I would like my assemblers to return different data based on which user is currently logged on (for instance to show that specific user's to-do list). To do this, I added a userId property to my spring security principals (by subclassing org.springframework.security.userdetails.User) and added user_id columns to user-specific data in the database. Now I would like to know how I can get the currently logged on user in my assembler so I can use its userId to fetch the user's data. Is the assembler the right place to decide which data to send to my flex application? If so, can anyone tell me how to determine which user is currently logged on in my assembler? If not, what would be the recommended way of dealing with user-specific data in my database in combination with blazeds? The only examples I have been able to find on the Internet so far only use different roles to determine what a user is or is not allowed to do, I have yet to find any examples where users store and retrieve user-specific data.

But if I try to size a child of that custom component, no width or height is assigned, unless I use an explicit setActualSize. For example: My custom component (Content) has been added to a canvas. The component is sized using width and height properties: var content:Content = new Content; content.width = 800; content.height = 800; addChild(content); In content, in createChildren, I create an instance of the Image component. var container:Image = new Image; container.scaleContent = false; addChild(container); I try to do this: container.percentWidth = 100; container.percentHeight = 100; But nothing.

Re: [flexcoders] Sizing Components Inside Custom UIComponents
Which you need to do from updateDisplayList() :) Also, keep in mind that if you set width and height on a child component directly rather than calling setActualSize(), that child component will no longer measure() and you'll only be able to get the dimensions you assigned to it rather than the dimensions it thinks it needs to be. -Josh On Wed, Jul 2, 2008 at 9:39 AM, Alex Harui [EMAIL PROTECTED] wrote: Parents size their children in Flex.
