Grouper Users - Open Discussion List

["Waldbieser, Carl" <>]

Chris,

I still haven't been able to pinpoint why some groups cause this error.
I tailed the logs today and got a more targeted error from the grouper_error 
log (see below).  It looks to me like the issue is that the code is trying to 
reference the 'guiGroupOwner' property on some object-- but I am not sure 
what that means in terms of what I ought to look for that makes this group 
different from one that does not exhibit the behavior.

I can reproduce the errors pretty reliably.

Thanks,

Subject: RE: Error - new ui - This group's membership in other groups

I hope there is a stacktrace or more info in the logs you can send along...  

In fact, if you know which group causes the problem, maybe turn off the UI, 
clear out the logs, turn on the UI, reproduce, and send the entire log file 
to me.

thanks, Chris

I received the following error when using the "This group's membership in 
other groups":

    Error: Problem converting JSP to string: 
/WEB-INF/grouperUi2/group/thisGroupsMembershipsContents.jsp, Problem calling 
method thisGroupsMemberships on 
edu.internet2.middleware.grouper.grouperUi.serviceLogic.UiV2Group

I noticed this in our development environment.  It does not happen with every 
group.  I was wondering if anyone else had noticed this?

Thanks,
