Editable table null exception when changing cell

I have a table that I made editable. When a cell is changed I use the cell edited event and run an update statement. The problem is when a column is initially NULL and I try changing the value of the that columns cell I receive a error “Uncaught NullPointerExcetion”. Even if I change my code to just print a string I still receive the error when trying to change the null cell.
If the cell is not initially NULL and I try editing, the cell updates with no errors.

Again, thanks for the report - this will be fixed in 3.3.1 as well.
