Hi,
the error occurred with ULC 6.1.2 and ULC 6.1.3. Now we are using 6.1.3.
We checked the ULCSession and UISession just before the fireTableDataChanged
call. I my opinion both seems to be alright. The output of the getSession Debug
Expressions and the failure trace is appended.
Best Regards
Frederik

Hi,
Which version of ULC are you using?
It appears that the session has terminated andgetSession() is returning null.
Thanks and regards,
Janak

Subject: [ULC-developer] NullPointerException calling
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
