> See attached for an example. I think this is down to two things:
> https://github.com/apache/flex-sdk/blob/develop/frameworks/projects/spark/src/spark/components/gridClasses/DataGridDragProxy.as
> element.getLayoutMatrix() is returning null. Doing a check for a null matrix,
> and returning an identity matrix seems to help
> https://github.com/apache/flex-sdk/blob/develop/frameworks/projects/spark/src/spark/components/gridClasses/DataGridDragProxy.as#L201
> I think this should be inside the loop, (at line 198)
