I have implemented this interface in Beta1 and it works just fine for
me... did you specify "implements IDropInListItemRenderer" in your
class declaration? For example, mine looks like this:
public class PivotTableCellRenderer extends mx.containers.HBox
implements IDropInListItemRenderer
The rest (the getter/setter methods) were a cut and paste from the
docs with the exception of TWO things... the internal variable in the
documentation has two underscores (__listData vs _listData) I make
mine all use one underscore. I believe that is better practice.
Also, the documentation references "FlexEvent.DATA_OBJECT_CHANGED"
which doesn't exist, so I've just called it this way:
this.dispatchEvent(new Event("dataObjectChanged"));
Hope this helps... I always hate the "It works for me" answer, but it
does =)
good luck,
Thunder
