You should be constraining the value by setting a validator on the
celleditor when the descriptor constructs the cell editor.

I'm having the same problem; I posted a question on Dec 16, but didn't
get an answer so far. In my case, the problem is that the displayed
value may differ from the value the user entered (stripped spaces etc.),
which causes the property to be set twice. I'm still looking for a way
to prevent this.
