Did you add some sort of double-click logic to the DG? The basic example only uses single click for selection. The selectionIndices should change and then the checkbox renderer should call isItemSelected and check the box if needed.

But the checkbox is only selcted when the checkbox is view area of the grid.If you scroll through the last column and double click the last column while you are not able to see the checkbox, the checkbox does not becomes selected. The challenge is how to make it selectable even if the checkbox is not visible. Any pointers... Thanks ilikeflex -- Alex Harui Flex SDK Team Adobe System, Inc. http://blogs.adobe.com/aharui
