invalidateList requests validateDisplayList call in the next frame update. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of tonmmp Sent: Thursday, March 22, 2007 12:04 PM To: [email protected] Subject: [flexcoders] Re: RTE when using itemRenderers in DataGrid.
