[jira] Commented: (TAPESTRY-632) Bug with "ForBean" when upgrade from beta5 to beta6
[ http://issues.apache.org/jira/browse/TAPESTRY-632?page=comments#action_12323008 ]
Wouter de Vaal commented on TAPESTRY-632:
-----------------------------------------
I get this too. It happens when you create a page with an empty contrib:table.
Tapestry tries to read hidden fields with the serialized data for the rows, but there is none, not
even an empty array and thus throws nullpointerexception on the line commented above.
I'll add a stack trace for convenience
