Grouper Users - Open Discussion List

[Martti Jokipii <>]

Hello,

We are running grouper-1.5.2 under Tomcat 6.0.24 with Oracle 11g as the 
backend database. I have noticed the
following behaviour when using Grouper as a user that belongs to wheel group:

- when I click [Act as self] 'Create groups' or 'Manage groups' in the UI, 
the 'Error!' indicator will be displayed and the following error message is 
shown (on our case via log4j) in Tomcat logfile:

2010-03-27 09:04:43,697 Tomcat6: [ajp-8009-2] ERROR:

Any ideas, what causes that?
