Glad to hear that your problem is solved.
I'm going to open an issue about this problem.
It might be useful for others as it was for us.
About why does it happens when SelectionModel is set, I guess that the
SelectionModel forces an update on the click. So it just anticipates this
unexpected behavior. If you don't use SelectionModel you still realize that
EditTextCell fires update when you click on the cell for editing, and click
out with no changes (that was my exactly problem).
The abstract popup cell concept seems to be very extendable. It would be
interesting to have such a feature.
Eventually, if the EditSelectCell component will be useful for you, you can
email me and I'll share it with you.
