Can I see the code where you instantiate the DataGrid? Feel free to send it directly to me off-list. Remove [flexcoders] from the subject if you can.

I already filed the bug (ASC-2894) this morning stating explicitly that I can't reproduce the problem outside the original application (Even other test applications in the same project don't have this problem). Basically its just evidence in case someone else comes across the same problem later. Feel free to close it due to lack of reproducibility. - Dan Freiman On 10/22/07, Alex Harui <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: I'd like to see the test case before you file the bug. ________________________________ From: [email protected] [mailto: flexcoders@ <mailto:flexcoders@> yahoogroups.com <http://yahoogroups.com> ] On Behalf Of Daniel Freiman Sent: Monday, October 22, 2007 11:07 AM To: [email protected] Subject: Re: [flexcoders] DataGrid not initializing default styles No modules.

I'm not sure how to solve it yet. I've tried cleaning the project which didn't work. I guess if all else fails I can copy _DataStyleGrid.as from the generated folder and manually instantiate execute it, but I'd rather it work correctly if possible. Any thoughts/advice would be appreciated. Thanks, - Dan Freiman On 10/20/07, Alex Harui < [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: The style chain is broken or damaged.

Also, the second error is thrown after user interaction with the PopUp (not user interaction with the DataGrid though) so it's definitely been created already before the second error. - Dan Freiman On 10/19/07, Alex Harui <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: Could you be centering a popup that hasn't been addPopUp'd? ________________________________ From: [EMAIL PROTECTED] ups.com [mailto:[EMAIL PROTECTED] ups.com <http://ups.com> ] On Behalf Of Daniel Freiman Sent: Friday, October 19, 2007 4:52 PM To: [email protected] Subject: Re: [flexcoders] DataGrid not initializing default styles Nope, it's just a plain DataGrid. All I touched was percentWidth/Height, minColumnWidth, draggable/resizableColumns and dataProvider. It's in the same popup as my earlier layout bug (Nested containers inside a PopUp.) Although I haven't been able to recreate in a contained example yet. - Dan Freiman On 10/19/07, Alex Harui <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: Did you subclass DG?
