are you asking how to reset an arraycollection back to zero values?

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. _____ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of jovialrandor Sent: Sunday, April 06, 2008 5:13 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: How can I clear an ArrayCollection or Datagrid 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?
