Description Ian Springer 2012-02-11 01:30:35 UTC

The following line is the culprit:

List<Resource> resources = query.getResultList();

It instead should be:

List<PluginConfigurationUpdate> resources = query.getResultList();

Here's the full stack trace:

Comment 1 Ian Springer 2012-02-13 15:02:52 UTC

It looks like this is a regression caused by the fix for BZ 737196 which was checked in on 10/5/11 (http://git.fedorahosted.org/git/?p=rhq/rhq.git;a=commitdiff;h=b9aada4).

Comment 2 Ian Springer 2012-02-13 16:52:54 UTC

To reproduce this, initiate a group plugin config update (e.g. across a group of JBoss AS Servers), and then go back to the Inventory>Connection Settings subtab while that group plugin config update is still in progress.

Comment 3 Mike Foley 2012-02-13 16:59:33 UTC

per triage 2/13/2012 (asantos, crouch, foley, loleary)

Comment 4 Charles Crouch 2012-02-13 17:03:48 UTC

So from Ian's comment this only occurs while a group plugin configuration update is in progress. Keeping Target Release as JON3.1.0

Comment 5 Ian Springer 2012-02-14 22:09:21 UTC

Fixed in master:

Comment 6 Mike Foley 2012-03-21 19:48:46 UTC

verified in master

Comment 9 Heiko W. Rupp 2013-09-03 15:09:08 UTC

Bulk closing of old issues in VERIFIED state.
