I'm sure that there are a number of ways you can do this, among them
coding a data descriptor class that implements the IDataDescriptor
(http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Book_Parts&file=about_dataproviders_057_15.html)
or renaming your Item.data field to Item.children so the
DefaultDataDescriptor would work with your class.
package
{
import mx.collections.ArrayCollection;
[Bindable]
public class Item {
public var name:String;
public var category:String;
//public var data:ArrayCollection;
public var children:ArrayCollection;
}
}
We recently ran into a situation where we wanted our Tree to use an
array of objects returned from a CFC as the data provider and still
take advantage of the auto conversion of remoting.
We weren't in a position to have the CFC return a
property named "children" and let the DefaultDataDescriptor handle it,
so what we ended up doing was adding a get function (property) named
children that returned the ArrayCollection being returned by the CFC
under a different name:
package {
import mx.collections.ArrayCollection;
[Bindable]
[RemoteClass(alias="SomeSite.cfc.AuthorVO")]
public class AuthorVO {
public var name:String = null;
public var publisher:String = null;
public var books:Array = null;
public function get children():ArrayCollection {
if (books== null) return null;
var ret:ArrayCollection = new ArrayCollection();
ret.source = books;
return ret;
}
}
}
This doesn't break the auto conversion of the CFC to the Flex class
and could be used for your situation as well:
package
{
import mx.collections.ArrayCollection;
[Bindable]
public class Item {
public var name:String;
public var category:String;
public var data:ArrayCollection;
public function get children():ArrayCollection {
return data;
}
}
}
Hope this helps!
