Issue in using Role in Mail notification in Workflow

Dear All,

As per the client requirement I have to send the UWL link with the workitem id in the email to lotus notes and I have configured the extended notification to send the email to the managers with the link to take action for the task and it is working fine.

But for other task the agent expression we are using is the ROLE and I want to send the same notification with the link to all the user in the role .

It is not working as in the email notification for the workflow we don't have the option ROLE/RULE to send the email to group of people.

Please advise.

Thanks.

Mustafa
