Any reason you can't go to Flex 3? That's probably messing up your popUp itemEditor too.

Hoping someone can give me a workaround or confirmation that this is a known issue (possible fixed in flex 3?) I'm using 2.0.1 hotfix 3. I've got two different crashes, but both have the same sort of symptom - when scrolling to the right as result of a TAB, if the next editable column uses a checkbox as an item renderer, the grid will throw an exception. Both grids have locked columns. In both cases the checkbox column is offscreen initially, but the tab from the rightmost visible column should scroll the checkbox column into view and then set focus on a cell in the checkbox column. In the one case I've tried to debug, it looks like listItems has not been updated to be in sync with horizontalScrollPosition. I've got 3 columns of interest in this scenario: column 6 is editable text, column 7 is non-editable text, column 8 is an editable checkbox. Initially, column 6 has focus and columns 7 & 8 are not visible. When I tab out of column 6 focus moves to column 8, but DataGrid.itemEditorInstance is not my Checkbox class - it's an instance of DataGridItemRenderer corresponding to the non-editable text in column 7 - as soon as I tab out of column 8, then things go south in itemEditEnd because itemEditorInstance is not really the item-editor. I stepped into createItemEditor - as near as I can tell, the column index is correct, but horizontalScrollPosition and listItems are not in sync with each other. Anybody seen this? Thanks
