Hi Alex, It turned out, the error below is caused by setting the DataGrid.editedItemPosition property with an object that has invalid rowIndex attribute value. For example, having a rowIndex greater than the number of rows in the datagrid.
In retrospect it would have been more helpful to get an error message directly indicating the invalid row (or column) index. Nonetheless I'm glad to have root-caused it. Should this be filed as a bug, if it hadn't been yet? Thanks. ________________________________ From: Alex Harui <aha...@adobe.com> To: "flexcoders@yahoogroups.com" <flexcoders@yahoogroups.com> Sent: Thursday, June 3, 2010 22:02:43 Subject: Re: [flexcoders] DataGrid error when scrolling to last row and starting item edit Can you reproduce the problem with a generic two-column DataGrid?
