            I've finally upgraded from Beta3 to current version, and of course
some things broke.

I've traced the latest problem back to a LiveDocs example** I based my
code from which generates the error:

TypeError: Error #1009: Cannot access a property or method of a null
object reference.
	at MyRenderers::MyTreeItemRenderer/set data()

// Override the set method for the data property
        // to set the font color and style of each node.
        override public function set data(value:Object):void {
            super.data = "">
            if(TreeListData(super.listData).hasChildren) {
                setStyle("color", 0xff0000);
                setStyle("fontWeight", 'bold');
            }
            else {
                setStyle("color", 0x000000);
                setStyle("fontWeight", 'normal');
            }
        }

I just can't see what's wrong with it what it might be in the "Flex 2
changes between Beta 3 and Release"
(http://weblogs.macromedia.com/flexteam/archives/2006/06/flex_2_changes.cfm
)
It's a bit of a show stopper at the moment...

any suggestions?
thanx
