If the service returned an empty AC, I would verify that the DG has
really been assigned that empty AC.  Read back the dataProvider on the
DG and see what its length is.  You can also try to manually reset the
DG to an empty AC and see if it refreshes that way.

Alex, the HTTPService returns an empty arraycollection, but the 
datagrid still has the values from the last call.

How do I in the code refresh the arraycollection, since the 'refresh
()' did not work?

Thanks
