Alan,
I know in LCDS that there isn't an analog for ArrayCollection. I'd try
having your nested VOs be simply an array and if you need to create an
ArrayCollection on the client side do so using your array of VOs as the
source attribute.

Subject: [flexcoders] BlazeDS, List of VOs inside a VOs won't
translate
Hi all,
I'm having trouble with BlazeDS and a particular VO that lives
inside another VO. The parent VO translates just fine, but I can't cast
the ArrayCollection of VOs inside that for the LIFE of me.
Actually the smaller one is a List in Java, so I am trying to
cast it to ArrayCollection.
I get the error: (And I know it to be from the below
ArrayCollection/list:-)
TypeError: Error #1034: Type Coercion failed: cannot convert
[EMAIL PROTECTED] to mx.collections.ArrayCollection.
This occurs when I try and iterate through the list of
urlButtonVOs. I've tried casting it to an ArrayCollection with NO luck.
Charles Web Debugging proxy tags it as an "External Object" and
recognizes it's Java class name. Every other object is an Object in
Charles. What makes this one special? It's an AC of a custom Object,
which has a definition and RemoteClass tag on the Flex side to match.
On the Java side I have:
public class CatalogItemVOX implements Serializable {
......
protected List urlButtons;
.....
}
And urlButtons happens to be a List of a class called
UrlButtonVO. It won't translate to an ArrayCol
On the ActionScript side I have:
[RemoteClass(alias="com.plateausystems.elms.client.struts.learner.catalo
g.CatalogItemVOX")]
public class CatalogItemVOX {
...
public ArrayCollection urlButtons;
...
}
I'm TOTALLY stuck. The info shows up in Charles, but I can't get
it to be recognized as an AC of that object type. Here's where the
exception is thrown: (The for each) casting data.urlButtons to an AC
doesn't work either. BTW: It's inside an item renderer)
public function onCreationComplete(): void
{
var buttonID: int=0;
for each(var button: UrlButtonVO
in data.urlButtons) {
var newButton: URLButton=
new URLButton();
newButton.id=String("button"+String(buttonID));
newButton.label=
button.label;
newButton.URL= button.url;
newButton.addEventListener(MouseEvent.CLICK, buttonClickHandler);
this.addChildAt(newButton,
buttonID);
buttonID++;
}
}
Thanks in advance to anyone that can help!
