Here is our ticket in case you want to reference it:
Case #897209 - 9.1 Wiki Tool breaks Groups API
Here's an extract from the ticket communication:
"You are correct it's an issue with the class loader that was resolved in Sp7. The BUG AS-157113 log4j Logging Issue in building blocks was also responsible for the 500 wiki error message Access to Wikis Error page HTTP status 500 Conflict with the Swing Jar.
These were changes not to our wiki tool but to our apis and tomcat classloaders."

Hi Malcolm
That's interesting, as it differs from the advice they gave us - do you know if that is in the standard SP7 release, or part of HF1? If not, I will ask for an update to our call.
Thanks
Simon

Roger,
This problem occurs because when third party code (e.g. a building
block) tries to persist a Group, the Blackboard wiki tool gets involved.
The Wiki tool runs with the permissions defined in the bb-manifest.xml file for the third party building block. Unless this is very generous with permissions the wiki tool will probably not have the permissions it needs and throw an exception. If you have building blocks that create Groups you'll need to watch out.
This still hits us on 9.1 sp6. I put a ticket in with Bb - they said it is fixed in a rewrite/update to their wiki tool in 9.1 sp7.
HTH
Malcolm.

Subject: Problem with wiki building block causing group errors?
Dear all
Does anyone recall a problem whereby the Blackboard wiki building block caused errors in group functionality? When testing BB 9.1 SP6 for our upgrade this summer we found that having the Wiki building block switched on led to errors when trying to create or edit groups. When the wiki was switched off the errors disappeared.
I think the problem has been fixed since the summer, but am just trying to verify this.
Many thanks
Roger
