I can send you the 2 affected beans. The first version is the working
version, the other one is the non-working, stacktrace-producing version.
Additionally I attach 2 support classes that you may want to check out.
For the next week I'll try to implement the beans back into the WSEP
(counting of projects and users, see the non-working bean).
Best regards
