Ümit, That's exactly what I've done. I've overridden the method setRowData(int, List<T) of my internal CellTable since I have control over that instance.
But what if I had not? Like, what if the CellTable instance was a parameter or something? Wouldn't it be interesting if HasData allowed the addition of another event type, one that would be fired after the table contents are changed? Should I open an enhancement issue?
