[flexcoders] VO problem
Hi List, I have some problems with my ValueObjects. First I give you my system configuration: SuSE Linux 9.2 Tomcat 5.5.7 Flex 1.5 Eclipse 3 Java 1.5 In my application I have Java Value Objects on the server side and I mapped them to my ActionScript 2.0 with Object.registerClass(). My problem is FLEX seems not to notice changes on the Java Value Objects. If I add a variable to the Java VO and the AS2 VO FLEX doesn't show it. I started tomcat again, no change. To check if I did the AS2 VOs correctly I used Java2AS written by Christophe Conraets. Here is the same effect. I change the Java VO, restart FLEX and Java2AS shows no change. I checked the class file created by Java, the changes are in there. The Java VO works fine in Java, every change is in it and the class file is composed in the WEB-INF/classes directory of my FLEX app. I'm a little bit confused. Is there any cache or something like that I can delete? Or is there anything in the flex-config.xml I didn't notice? I appreciate for any help.

[flexcoders] Re: I need assistance with datdgrid row height.
yes, the problem is that I am using a textArea in the cell renderer and I can't set the height of the textArea to something like a variableRowHeight. I just created to columns, which I was trying to avoid but no big deal, and got rid of the cell renderer. thanks though. --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: Did you also set wordWrap=true on the appropriate DataGridColumn?

[flexcoders] unable to invoke right clicking in apllication
I want to implement context menu for different components in my application. The right click need to be implemented in Tree, DataGrid and TileList. My context menu is the same as given in Chapter 10 of Developing Rich Clients with Macromedia Flex, Components: Designing for Resuability. I want to show dynamic context menu item based on where the user has right clicked in the Tree. The tree is in panel having linkbar above the tree. Now when i right click on the tree, the right click only works on the panel and linkbar but does not work when i try to right click on tree. The correct menu Item does not appear when I right click on the tree. I want the right click to function only on the tree and not on panel. I have attached with this mail the code i am working on. It would be great if someone could help me out with this. Yahoo! India Matrimony: Find your life partner online Go to: http://yahoo.shaadi.com/india-matrimony Yahoo!

RE: [flexcoders] right mouse click in flex
Hi, ContextMenu only works with top-level objects in Flex application. ContextMenu wouldn't work with any nested object/component, I believe that is why it is not working with Tree in your case. Macromedia Flash Player team is looking into this issue and we hope it gets resolved in future version of Flash Player. For now, you can have ContextMenu at application level and show relevant menu-items by finding out where mouse is, when right-click happens. Please search the flexcoders archives, there has been some discussions on the same. http://www.mail-archive.com/flexcoders@yahoogroups.com/ Hope that helps...

RE: [flexcoders] Converting Java POJO to Actionscript Errors
Hi,
First couple of questions - did you register your POJO with AS class
using Object.registerClass( ) method?
What is the constructor method of you Pojo ?
After both of above are in place(implemented) then you can create new object
of your POJO type and assign your newly returned object to it and then add
this new object to your datagrid using myDataGrid.addItem( );
This is what I did.
AS class looks like
class classes.MyPojo
{
public var myArray:Array;
private static var registered:Boolean = Object.registerClass(full path
of you java class goes here, classes. MyPojo);
}
In my MXML you can ignore statements which sets initial attribute
values
function addRow()
{
var oNewItem:Object = new MyPojo ();
oNewItem.adj_num = 12 ;
oNewItem.adj_type = ;
oNewItem.adj_category = ;
oNewItem.adj_amt_terms_desc = Doodi;
oNewItem.adj_reporter_applied_flag = N;
oNewItem.adj_sign = Additive;
oNewItem.adj_factor = ;
oNewItem.adj_order_applied = 12;
myDataGrid.addItem(oNewItem);
focusNewRow();
doLater(this,focusNewRow);

[flexcoders] Data Binding and Server Objects
If I'm getting objects from a web service and want to use them in
data binding, do I have to re-create them in ActionScript in order
for their various properties and sub-objects to be bindable?
Ideally, I'd like to just use what the server gives me and not
rewrite the objects in AS. i.e.:
(in my ModelLocator)
public static var userInfo:Object;
(in my GetUserCommand)
ModelLocator.userInfo = event.result[0];
(In my mxml)
mx:Label text='{Welcome, +ModelLocator.userInfo.firstname+
+ModelLocator.userInfo.lastname}' /
Is it possible to get this to work like that? or will ModelLocator
need to have something like:
public static var userInfo:UserVO;
function ModelLocator()
{
ModelLocator.userInfo = new UserVO();
}
class com.app.path.UserVO
...
I'd rather avoid having to create all the server side objects on the
client side; they come from the web service strongly typed, which is
good enough for me, but does Flex need to have all of the bindable
properties defined at complie-time for binding to work?
Thanks,
Sean

Subject: [flexcoders] Tree change
event
Hi,
I noticed that the trees change event does not work
as expected ( the same way as for example in DataGrid ). When a user selects a
node on a tree, the tree sends change event properly, as in DataGrid. But when
the user deselects (is that a word?) a node by clicking it with CTRL key
down, it does not send change event (as datagrid does). This causes real
problems, since I get no info that the there are no nodes now selected ( as
user has done something I can not follow) and my buttons that should be
disabled when no nodes are selected, stay enabled - leads to errors.
Is there a fix or a nice workaround on this issue?
Is this a feature or a bug in the Tree?

RE: [flexcoders] Converting Java POJO to Actionscript Errors
(Hi suzy, firstly, I'm a little confused as to how Kevin Ewok's response
turned into your message - are you saying you're having the same issue
as Kevin? Let me first comment on Kevin's issue which will provide good
background for yours...).
On looking again at the warning Keven is getting from ClassUtil it means
that he didn't link in the com.MyPojo class to his SWF... that is, the
compiler didn't include the AS class because it wasn't referenced
anywhere.
Having a dummy variable of com.MyPojo type is one way to cause a
dependency on that class to have it compiled and linked in to the SWF.
But, furthermore, by using Object.registerClass() you can avoid the
ClassUtil issue altogether because the player will attempt to create
types for you from the registerd information while processing the AMF
response before the ClassUtil gets a chance to look at the result.
The ClassUtil is a legacy system from Flex 1.0 SOAP-based RemoteObject
(which is not supported in Flex 1.5) where by you could use a special
_remoteClass property to map client/server types since
Object.registerClass wasn't useful for non-AMF communication (i.e. XML
transactions are just strings and thus don't' get processed by the
player). Since Flex 1.5 RemoteObject only uses AMF, the _remoteClass
method is not suggested for Flex 1.5 and you should use
Object.registerClass().
Now, for Suzy's question...
Essentially what you're looking for here is that Remote POJOs turn into
plain old dynamic Objects on the client, right?
The problem is that in Flex 1.5 RemoteObject still has the deprecated
_remoteClass property in the response (which you should be able to see
in the AMF trace output).
The old ClassUtil is designed to always do this translation for you if
it finds the _remoteClass property... that is, it expects that typed
POJOs map to a corresponding AS type (that must be available at runtime
from the SWF).
By calling Object.registerClass you could bypass the ClassUtil's
translation attempt altogether... and, actually here's an idea, perhaps
you can trick the player into registering your remote POJO class to just
plain old Object to get a dynamic object back?

THanks for your response. I tried that but I got a

Thanksto answer your confusion...Suzy and Kevin are the same

Getting back to your response (thanks by the way), I've tried

errors. I tried issuing the Object.registerClass() method to my Java

seems like a poor design to me. I see there are some Ant scripts out
there that do this, but they don't generate the class for me if there
is inheritance. I would think there's a way I can just plug the
returned single POJO in the datagridafter all, the datagrid was

RE: [flexcoders] Re: Converting Java POJO to Actionscript Errors
I've tried assigning the returned remote object to a general AS object (see example below)...that does not workthat's what causing these errors. [Pete] The hack I meant was something like this (I've not tested this, just something I guessed might work): static var reg:Boolean = Object.registerClass(com.MyPojo, Object); I tried issuing the Object.registerClass() method to my Java POJO w/i my mxml file where I load the Datagrid...that does not work either. [Pete] Do you mean you tried to register com.MyPojo as type Object as with the above syntax, or do you mean you tried registering it to an AS type matching com.MyPojo? Object.registerClass() in general does work... there must be something that you're not doing correctly that we can try to solve. I listed several possible causes in my previous email. The obvious one is that the AS representation of your Java object(s) must be linked in at compile time (the evidence for this is the ClassUtil error that you received when not using Object.registerClass()) in order for the player to deserialize the type from AMF to the AS type. If the mention of the AS class in the second parameter of Object.registerClass doesn't seem to add a compile time dependency, can you try adding your own dependency on the class like this: private var dummyVar:com.MyPojo; I guess I will be forced to write the AS class that matches my POJO... ...writing the same class twice seems like a poor design to me. [Pete] I disagree - the vast majority of RemoteObject applications that need non-simple types have a client and server representation of ValueObjects. The transfer of the object over the wire is merely the state. Many applications require client and server methods on the object. After all, the datagrid was first populated with an array of the SAME POJOs w/o having to register any classes!! [Pete] How so? Yahoo!

[flexcoders] Re: Converting Java POJO to Actionscript Errors
OK...i've gotten a lot further. I found an Ant script to create my AS
classes from my POJOs (maintaining inheritance). I registered the
classes and it compiles fine. THe problem is still there but it looks
like the POJO being returned from myRemoteObject is not being
converted to it's AS counterpart. When I debug, the 'result' is
'undefined'. I debugged my Service class and I see the data is there.
What am I doing wrong where the AS class is not getting populated
correctly? Is it because I have my dataprovider set to a remoteObject
result? Should I set another varaible for that? Thanks

RE: [flexcoders] Re: Converting Java POJO to Actionscript Errors
Is myValue on oNewItem a complex type or is it expected to return a
simple value?
Does the constructor of com.MyPojo take any arguments? If so, does it
look something like this?
public class com.MyPojo
{
public var myValue:String;
public function MyPojo(mval:String, someval:Object ...)
{
myValue = mval;
// set other vals...
}
}
If so, then you're getting bitten by the deserialziation order of the
Flash Player for complex types. When the player is recreated instances
of types from their serialized form (be it AMF, RTMP, LSOs), it first
creates a shell instance from the type, sets the state, then calls the
real constructor (with no args defined). This is by design because
serialized objects can't pass constructor arguments so by setting them
first you get a chance to access them during object initialization...
but it does mean that blindly setting the values from constructor
arguments is dangerous as it will override the member variables with
undefined (as no arguments were passed to the constructor).
Try this check first:
public class com.MyPojo
{
public var myValue:String;
public function MyPojo(mval:String, someval:Object ...)
{
if (mval != undefined)
{
myValue = mval;
// set other vals...
}
}
}
(Note: For the keen AS2-savvy engineers out there, you could use the
!== or strict not-equal operator to allow for null values to be passed
to constructors when not being initialized by deserialization).

What am I doing wrong where the AS class is not getting populated

that he didn't link in the com.MyPojo class to his SWF... that is,

Re: [flexcoders] Re: Converting Java POJO to Actionscript Errors
Kevin, here's one other thing to try if Peter's advice isn't relevant:
Often, an AS class that is mapped from a POJO will not be referenced
anywhere in the application code, since it only arrives in the
application as a result of being deserialized. What happens in this
case is that the MXMLC compiler does not link the AS class into the
application, and deserialization will fail silently in pretty much
exactly the way you describe. It looks like the object arrives from the
debug printouts, but AS code will behave as if it's undefined.
(I wasted about 4 hours debugging this case yesterday, so it happens.)
To avoid this, somewhere in a class that *is* being linked, include the
following line:
static var myPojoDependency:Function = com.MyPojo.
Alternatively, just include another cop yof the Object.registerClass()
call for MyPojo in a class that is already being linked in.

Re: [flexcoders] Resizing SWFs in mx:Loader
Hi Tim, You're using an image component, and not a loader component. Once you change to a loader component, you can do the following: I get the size of the SWF being loaded into the loader component and then resize the loader component to the size of the contents. By doing so, I can control the surrounding objects, too, if need be. We had built a much more complicated app in Flash with a loader component that needed its own resize engine for layouts. Here's pseudo-code: //load swf controls go here. // get size of contents loaderHeight = media_ldr.content._height loaderWidth = media_ldr.content._width // media_ldr.setSize(loaderWidth,loaderHeight); Dave Yahoo!

[flexcoders] Flash Remoting bug in Map handling
Hey all,
This is both an FYI and a query to see if anyone has a solution to this
issue.
There seems to be a bug in Flash Remoting in the handling of
java.util.Map keys.
Setup:
Flex 1.5
Remoting configured with
serializationFlex/serialization
lowercase-keysfalse/lowercase-keys
The issue is that Map keys are always made lowercase. The issue appears
to be in the deserializing of objects of type 'ECMA Array' coming from
Flash.
To reproduce create a Java service:
public class RemotingService
{
public Map getMap()
{
Map map = new HashMap();
map.put(Uppercase Key, value);
return map;
}
public Object echo(Object obj)
{
return obj;
}
}
Using these services in Flex to reproduce this bug as follows:
1. Call getMap() to get the map instance from the server
2. trace the map keys - the key will still be mixed case
3. Call echo() with the map as argument
4. trace the returned map keys - the key will be all lowercase
It seems to me that the Map contents should be able to round trip
without modification.
Turning on debugging in the gateway, I you can see that the type of the
map is 'ECMA Array'. There doesn't seem to be a way to create an ECMA
Array in ActionScript. You can only get one back from a Remoting call.
I need my Map key case to be preserved. The only workaround for this
issue I can think of is to clone the Map contents into an ActionScript
object before sending it back to the server:
var clone = {};
for (var p in map)
{
clone[p] = map[p];
}
This does work - the gateway debugging shows that this is now of type
'Object' which correctly becomes a Map with key case preserved in Java.
Anyone got any better ideas?

[flexcoders] Re: Custom ComboBoxCellRenderer Issue
You're not missing anything. There's a super-secret mouseDown
handler in the datagrid that is messing you up. Lots of folks have
tried various ways to workaround it and I think they've succeeded.
Last time we tried it, we subclassed the DataGrid and overrode its
onMouseDown method to see if it hittest the combobox which is acting
as the cellEditor
function onMouseDown() : Void
{
var pt = new Object();
pt.x = _root._xmouse;
pt.y = _root._ymouse;
_root.localToGlobal(pt);
if (cellEditor._visible cellEditor.isCellEditor)
{
if (cellEditor.hitTest(pt.x, pt.y))
return;
// if comboheight 30, then dropdown is visible
if (cellEditor.combo.height 30
cellEditor.combo.dropdown._visible
cellEditor.combo.dropdown.hitTest(pt.x, pt.y))
return;
}
super.onMouseDown();
}
The the cell renderer watches for the close event on the combobox and
destroys its dropdown.
function close() {
size();
combo.dropdown.removeMovieClip();
combo.mask.removeMovieClip();

[flexcoders] Re: Panel Mouse Down Problem
There are some idiosyncracies when objects appear and disappear under
the mouse. In general, by listening to all mouse events (down, up,
over, out) you can see a pattern that you can look for (you may see an
over instead of a down for example).
In other situations, this can be remedied by not changing the object
under the mouse in response to a mouse event, which can be done by
taking the functionality in the mouse event, wrapping it in a function
and calling it via doLater.
function showAlertLater()
{
Alert.show(...)
}
mousedown=doLater(this, 'showAlertLater')
No guarantees, but we've worked around these kinds of issues
successfully.
