Hi Alan, the declaration of the urlButtons field in the AS object is a little off. it might just be that you typed it in, but just in case, it should be:
public var urlButtons:ArrayCollection; The value type should be converted automatically. I have an application running that has a list in the java side and maps automatically to an arraycollection. have you tried just putting a breakpoint before the foreach in FB and then inspecting the result, first making sure that the CatalogItemVOX is actually getting mapped to the response objects you received. After that, I'd manually inspect the CatalogItemVOX and see what its fields are. so, basically, inspect "data" and make sure its type is CatalogItemVOX. use the fb3 debugger too. /r On Tue, Apr 29, 2008 at 11:03 AM, Alan Prather <[EMAIL PROTECTED]> wrote: > Jeff, > > > > According to the documentation, all Java Collections will be automatically > translated to an ArrayCollection on the front end.
