Hi,
I'm generating a rich:DataTable with binding to backend bean - backend bean creates a list of rich:columns and adds to the dataTable.
Table is working fine for me, but after a few minutes I see this error in logs - apparantly a nullpointer exception while saving state of the dataTable - doesnt affect displaying or even refresh of the dataTable.
What should I do to eliminate the root cause of this NPE?
A part of the relevant log....
