Answer 1

I would be willing to bet that whoever wrote that was trying to get the datagrid to refresh after the underlying arrayCollection was updated somehow. The better way of doing this is to dispatch a CollectionChange event on the arrayCollection after the update is made.

Example:

myArrayCollection.dispatchEvent( new CollectionEvent(CollectionEvent.COLLECTION_CHANGE) );
