Thanks Thomas. I used the patched ActionCell and ButtonCell from the link you gave me from the issue and it worked great.
Using 2 ActionCells in a CompositeCell also worked. I think that is all I need to keep cellwidgets in production (users are great bugfinders! ;) ) . I hope the patch will make its way to the next version.
