Fixing possible exception on tables in tabs
Fixing possible exception on tables in tabs

When a filter action for instance goes to the server via POST, an
'action' field is not necessarily present in the POST. This results
in an uncaught exception. Fixing this so if 'action' is not present
falling back to old behavior.
