I have used AC API method removeAll() to clear an AC, and it properly updates the UI.
Assigning an empty AC should do it as well, though.

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: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of jovialrandor Sent: Sunday, April 06, 2008 5:13 PM To: [email protected] 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?
