Yeah, this is the tradeoff for not using FDS. As I see this, Flex is
unaware of the types passed thru SOAP from webservices. There is no
automatic mapping/casting types on-the-fly. Flex could try an automatic
mapping, but in the end, there will be more complex situations, where
some kind of external xml mapping is needed.
I'm struggling with good solution for this one too. What I currently
have is an PO object, which I call Perspective Object, which is some
kind of mature object, created from raw VO (having public fields, for
example. VO on the other hand has privates). There you could specify
such methods as :
public static function transformFromObject(object:Object):BookPO {
return new BookPO(object.id, object.name, object.author);
}
public static function
transformCollection(collection:ArrayCollection):ArrayCollection {
var col:ArrayCollection = new ArrayCollection();
var cur:IViewCursor = collection.createCursor();
while (! cur.afterLast) {
var book:BookPO = transformFromObject(cur.current);
col.addItem(book);
cur.moveNext();
}
return col;
}
But I feel that there is something not right with setting properties by
hand. I've found this :
http://coldfusion.sys-con.com/read/264726.htm
on Sys-CON, but the solution provided there is even more unclear for me.
And oh, the isn't the RETURN_OBJ always an ArrayCollection of Objects?
(event.result, that is).
Hope this helps a little bit.
