I kept thinking about my problem and I feel that my “solution” feels more like a patch than a proper solution for a larger underlying problem.

 

Why would “GrouperSession.staticGrouperSession(false)” return an invalid session instead of “null” ? Shouldn’t it validate that the session is still active before returning it ?

I did more digging, and I think I might have a solution, does it make any sense or should it be done another way ? I’ll be testing it in the next few days since the problem seems intermittent.

 

GrouperUiFilter.java

Method : requireUiGroup (around line 380)

 

FROM :

          if (!PrivilegeHelper.isWheelOrRoot(grouperSession.getSubject())) {

            grouperSession = grouperSession.internal_getRootSession();

          }

 

TO :

        try {

          if (!PrivilegeHelper.isWheelOrRoot(grouperSession.getSubject())) {

            grouperSession = grouperSession.internal_getRootSession();

          }

        } catch (IllegalStateException ise) { // session is invalid, probably stopped, use a new one

          grouperSession = GrouperSession.startRootSession();

          startedSession = true;

        }

Hi,

I’m getting a very unpleasant error in the UI. I configured the “require.group.for.loginsand I believe it’s causing the problem. I’m running the 2.1.3 UI.

 

Often, when a user logs in, he will get the following error message(see screenshot). If he clicks on any link a few time it usually comes back. This screenshot was made using my sysadmin user, but it will do the same thing using a standard user. I tried looking in the source code using the stacktrace (see below), but didn’t get anywhere.

 

Is it fixable ?

 

Thanks

 

PS. Chris had a fix for me when I first tried a required group (it’s running now), I don’t know if it’s related or not : https://bugs.internet2.edu/jira/browse/GRP-840

Looking in the logs, I see the following :
