problem in Web Dynpro ABAP

Hello SDN,

I am facing a strange problem in Web Dynpro ABAP. I was added a new column (3rd One) in one view. Now it is not allowing to display the Layout tab. When ever I am trying to select Layout tab I am getting the Dump with message "OBJECTS_OBJREF_NOT_ASSIGNED_NO". Please provde me the solution for this otherwise my entire code changes will be lost and I will be in big trouble. Please help me out in this critical situation. Waitingfor your valuable response.

Regards,

Kumar.
