uwl cutomization Submit selected items Tab/button not displaying

Hi Team,

We have the requirement for Mass Processing of UWL tasks for Leave approval and we have done changes in XML by using the following blog.

http://scn.sap.com/community/enterprise-portal/administration-and-development/blog/2011/03/11/mass-processing-of-uwl-tasks-where-task-is-not-of-decision-type-task-like-standard-leave-request

After changes done successfully, I am able to see the check boxes, leave type, start,end date and AM/PM.

In this functionality we need to get the "Button" like "submit selected items" on top of the page while we selecting the "Leave management" type But "Submit User Decision" tab is not appearing in UWL.

It is Standard application which we are using but still we are unable to view the specific tab.

Please contact me anything needed from my side (mmbsap@gmail.com).

Thanks,

Basha
