Judah Frangipane updated FLEX-35028:
------------------------------------
Description:
When using a DataGrid if you click the header and the column index is -1 then
an error is thrown:
{code=actionscript}
public function getHeaderRendererAt(columnIndex:int):IGridItemRenderer
{
// TODO: fix this: do the work here, rather than the layout
const view:Group = getColumnHeaderViewAtIndex(columnIndex);
return
GridHeaderViewLayout(view.layout).getHeaderRendererAt(columnIndex);
}
{code}
view is null
Solution may be to check if index is not -1 and return null if it is
