Customize UWL task attachments in ce 7.2

Hi Experts,

We are using NW CE 7.2 sp05 and BPM. We need a solution for the below requirement.

1) When user opens the BPM triggered task from CE UWL we have to display the task attachments by default if the task contains any attachments.

2)  If user took action on the task either by approving or rejecting the task completes with a message "task completed successfully" and below that the opened attachment tab is still seen on the screen is there any way to hide that attachment tab.

Is there any solution / work around for the above will be helpful.

Regards,

Pradeep
