Grouper Users - Open Discussion List

[GOOD Richard <>]

Hi all,

we've recently upgraded our old Grouper 1.5 instance to 2.2 on DEV (with 
thanks to Shilen for assisting :)). We've noticed the following error when we 
look up certain groups (in the case below it's the sysadmin group):

Caused by: org.apache.jasper.JasperException: An exception occurred 
processing JSP page /WEB-INF/grouperUi2/group/groupHeader.jsp at line 170

167:                           </tr>
168:                           <tr>
169:                             
<td><strong>${textContainer.text['groupLabelLastEditedBy']}</strong></td>
170:                             
<td>${grouperRequestContainer.groupContainer.guiGroup.lastUpdatedByGuiSubject.shortLinkWithIcon}</td>
171:                           </tr>
172:                           <tr>
173:                             
<td><strong>${textContainer.text['groupLabelTypeLabel']}</strong></td>

If I understand the error correctly it's complaining that it can't find that 
unique identifier in our IDM which Grouper is configured to use as person 
source. I guess there are perhaps some internal groups to Grouper which are 
set with a particular subject id as owner, or our Dev IDM has somehow removed 
an account on which Grouper relies?

Should we create a functional account for Grouper in our IDM which has that 
ID in order to resolve that issue? Or is there some other configuration which 
I've missed? 

We're running on Tomcat 8 and JRE 1.8 in case that's relevant.

Thanks!

Richard
