Universal Worklist (UWL) Attachment Error

Hi

We're running EP6.0 and have recently upgraded to SP12. We have WP-PI 600-620 installed.

Following the upgrade a Universal Worklist attachement that was viewable in SP9, is no longer viewable.

It appears when rendering the task detail page, UWL already has decided the attachment is invalid. Here is the link for the attachment (the attachment is a URL)

http://server:50000/irj/servlet/prt/portal/prtroot/com.sap.netweaver.bc.uwl.ui.UWLInformation?key1=AttachmentError&key1_param1= Internal error .

Any suggestions?

Thanks
