   PickList.mxml appears to have two ways of setting the dataProvider.  One is in the handleResult which looks correct, the other is in the mx:AdvancedDataGrid tag where it binds to arrDGDataProvider which appears to be incorrect as handleResult is expecting an ArrayCollection of ArrayCollections.
   
   ```
   dataProvider="{arrDGDataProvider}"
   ```
   
   This causes the labelFunction to throw the exception as it is getting an ArrayCollection instead of the list of items.
