Error in iView "Universal Worklist"

In the (EP 6.0 SP 10) folder "Content Provided by SAP -> com.sap.netweaver.bc.uwl" the iView Universal Worklist can be found. When we execute it, it works fine, but as soon as we click on one of the items in the UWL (e.g. a Purchase order) we are simply getting a blank page. It seems like the link to the detail iView doesnt work - any ideas to what the problem might be will be appreciated and rewarded.

Best regards Kurt
