Not able to send UWL Notifications as Mail

Hi,

I implemented Guided Procedure with two roles.

The completion of activity / task of first role intimates the second role thru' UWL. I can see the activity / task for the second role in UWL once the activity / task is completed from the first role. But the Email Notification is not triggered thru the UWL for that task. Can any one help reg. this?

PS: I am able to trigger the Email Notifications for KM Workflow & UME.

Thanks in Advance,

Anish
