RE: [ULC-developer] NullPointerException calling fireTableDataChanged()

[Janak Mulani]

Hi,

Which version of ULC are you using?

It appears that the session has terminated and getSession() is returning
null.

Thanks and regards,

Janak

fireTableDataChanged()


  hi,


  we get a NullPointerException while testing a Table-component which
extends ULCTable. The Exception occurred while calling
fireTableDataChanged() on ower TableModel.


  I have no idea, to fix this Problem. Maybe you have any advise for me to
solve it.
  The following failure trace occurred:


  java.lang.NullPointerException
