Crystal Report Enterprise Error while using Group Tree.

Hi,

I am not sure if I am posting it in the right place.

We have designed reports using Crystal Report 4.0 with BEX as Data Source. The report is grouped on Product Hierarchy. When I open the Group Tree so that I can view the group by clicking on it. It works fine in CR 4.0 Desinger but it fails with an error msg whe we view it from the server using BI Launch Pad.

When I click on any of the node in the group tree it throws an error as "java.util.NoSuchElementException"

Can anybody suggest what this error is and how I can fix this.

We are using BO enterprise 4.0 FP 6 on both server and client.
