Adding columns to result list in inbox view of web client

Hi,

I have a requirement to display custom columns in result list of inbox view of web client. I copied the view and controller to custom name space. In BSP_WD_WORKBENCH , for AUIITEM view, there are two context nodes . AUIITEMTREE is one of thena and has tree structure and under it tree node proxy. Tree node proxy has attributes, I can not add more attributes to Tree node proxy in work bench. Would you please any one suggest the approach to solve this problem.

Thanks in advance.

With regards,

Ravi Kumar
