this is fixed in that an error is not thrown. It will log an error and not display the subject that cant be found 

maybe at some point we could have the API return a subject that has the subject id and source without all the other attributes... not sure if there are downsides to that (at least you would see the id on the ui)


See screenshot below.  Feel free to patch your env if you like J


Note, if you have a lot of subject not found exceptions, not sure what else in the UI wont work, if you notice something, let me know J

Subject: [grouper-users] Grouper 2.2 Error when trying to look at group in new UI


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

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.
