Jeff,
According to the documentation, all Java Collections will be automatically translated to an ArrayCollection on the front end. That seems to be the case for the list of parent VOs, but within them my lists don't translate to ArrayCollection. I'm not sure why, but it's something I can expand out in Charles, but I can't get it to cast to anything in Flex (EG, trying to cast it to ArrayCollection throws an exception. It's really weird. Something tells me that the reference to 'external object' in Charles must be a clue! Thanks for your input Jeff! Help! Anyone? Anyone? -Alan ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Battershall, Jeff Sent: Tuesday, April 29, 2008 1:55 PM To: [email protected] Subject: RE: [flexcoders] BlazeDS, List of VOs inside a VOs won't translate 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.

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! ______________________________ -Alan Prather .
