>             Project: Apache Flex
>          Issue Type: Bug
>          Components: mx: DataGrid
>    Affects Versions: Adobe Flex SDK Previous
>         Environment: Affected OS(s): Windows
> Affected OS(s): Windows XP
> Browser: Firefox 2.x
> Language Found: English
>            Reporter: Adobe JIRA
>            Assignee: Mark Kessler
>
> Steps to reproduce:
> 1. create a DataGrid with a custom header renderer that contains a button
> 2. run the app
> 3. click the button
>  
>  Actual Results:
>  Runtime error on line 3909 of DataGrid.as trying to dereference pos.y, when pos is null, presumably because of an invalid cast in the line above.  For some reason, 'target' is assumed to be the item renderer (an IListItemRenderer), but it is actually the DataGrid itself.
>  
>  Expected Results:
>  no error
