Flex ItemRenderer not passing mouseover to parent

Question

In an AdvancedDataGrid using an MXAdvancedDataGridItemRenderer, mouseover was not being passed on to the AdvancedDataGrid.
After days of struggle, I wanted to share this: In your data setter, assign super.data with the new value for mouse events to be bubbled (?!)

Example (doesn't work)

        override public function set data( value:Object):void {             
            var latency:Number = value[ ( this.listData as DataGridListData).dataField] as Number;

            // Do cool stuff

Example (works)

        override public function set data( value:Object):void {             
            var latency:Number = value[ ( this.listData as DataGridListData).dataField] as Number;
            super.data = value;

            // Do cool stuff

just declare super.data = value before var latency......

 override public function set data( value:Object):void {  
        super.data = value;           
        var latency:Number = value[ ( this.listData as DataGridListData).dataField] as Number;

For clarity, it works both ways. My point was if you assign super.data then mouseevents just work. – MonoThreaded Jan 06 '12 at 12:25

The example above works. Hope it can save you the time it took me to figure out.
