I see this error whenever i hover over the 'Activites' column in Volumes tab. I could not re-produce this error while doing all volume related operations but carefully not moving the mouse over 'Activites' column. 

Sas: Can u check and confirm?

Yes, I was under the impression that while performing 'volume' operations, I could hit this bug.

But I was hovering over 'Activities' column under volumes tab, after performing any volume operations from UI. That created an illusion the other way, which made me to think that any volume related operation is causing this issue.

Comment 6 RamaKasturi 2016-02-15 08:52:50 UTC
Ramesh, agree with you.

what i have observed is when we are doing some operations in activities column it is consistently reproducible and until we close them we cannot really perform any operation.

Comment 7 RamaKasturi 2016-02-15 09:18:43 UTC
Seen "uncaught exception occured. Please try reloading the page." when trying to create a new geo-replication.

Comment 8 Sahina Bose 2016-03-31 09:23:56 UTC
Can you attach the debug info logs to the bug? You need to install the webadmin-debuginfo package to get the logs

oVirt 4.0 beta has been released, moving to RC milestone.

Comment 11 Yaniv Lavi 2016-05-23 13:20:51 UTC
oVirt 4.0 beta has been released, moving to RC milestone.

Comment 13 Sandro Bonazzola 2016-07-12 09:58:14 UTC
Moving back to POST since this bug is targeted to 4.0.1 but the patch has not been included in 4.0.1 branch. Please check this bug status and eventually re-target to 4.0.2.

Comment 14 Ramesh N 2016-07-21 11:40:11 UTC
Moving to modified since the patch is already included in 4.0.2 rc1 branch.

Comment 15 RamaKasturi 2016-08-16 13:31:25 UTC
Verified and works fine with build ovirt-engine-4.0.2.6-0.1.el7ev.noarch.

Do not see any exceptions in the UI while creating volume, setting options, retrieving advanced details and performed rebalance,remove-brick operations.
