[news.eclipse.tools.gef] Weird problem with ICellValidator

[Pavan Podila <pavan.podila@xxxxxxxxx>]

Hi,
   I have attached a CellValidator for the TextCellEditor of my label. 
When I type my text in the TextCellEditor, the label size automatically 
grows. However when the isValid() of the CellValidator returns a string 
error message, the label size stops growing and resizes just big enough 
to fit one character. I am attaching the screenshots below for the two 
cases. What could be the problem?

thanks in advance,
Pavan
