PO approval notification custom URL header attribute

Hi,

I need to add a custom URL header attribute to the PO approval notification.

This notification uses OAF.

I've added the new attribute to the message with an internal name of #HDR_1 and type URL.

When viewing the notification from the user notification list the attribute is displayed as plain text rather than a clickable URL.

The email that the user receives does have the attribute as a clickable URL though.

Is there any way to make the link clickable on the notification screen?

Thanks
