Problems with deleting groups

torte Feb 19, 2013 5:12 AM

Hello RHQ Community,

i'am new to rhq and jboss. I'am new in this forum too. Please excuse if I'am doing something wrong or asking questions which are already solved.

At the moment i got the problem that i can't delete dynagroups which i created. I got a bunch of test groups and now i want to get rid of them.

Nearly the half of this groups are deleted without any problem but some groups can't be deleted. There is a message appearing like: "Failed to delete the selected group definitions"

If i go on Root Cause there is "java.util.ConcurrentModificationException:null"

If i go to "Show Details" i see this:

Message :

Failed to delete the selected group definitions

Severity :

Error


Time :

Tuesday, February 19, 2013 11:06:51 AM UTC+1

Root Cause :

java.util.ConcurrentModificationException:null

Detail :

java.lang.RuntimeException:[1361268411587] org.rhq.enterprise.server.resource.group.definition.exception.GroupDefinitionDeleteException:Error removing managedGroup 'DynaGroup - Test Dyn Connector' from groupDefinition 'Test Dyn Connector': -> javax.ejb.EJBTransactionRolledbackException:null -> java.util.ConcurrentModificationException:null

Anyone got an idea? I'am still hoping Iam doing something wrong or this is a known issue.

Thank you all for your attention.

Regards, Torte

I have found a way to delete these groups. I did remove all dyngroups which i want to delete from user roles. Still I'am confused about this. If anyone give me hint or a reference in the manual i would be very thankful.

Hi Torte,
we are aware of this issue and it has been fixed in the master branch. It will be available in the next release (4.6.0). If this issue is critical for you, you can clone the repo and build the RHQ from the latest source code. As you have correctly mentioned, it was related to user roles and the purpose of the problem was quite simple, here is the fix.
