Assuming it is storage.
--- Additional comment from Tal Nisan on 2016-08-08 06:09:30 EDT ---
Looking at the frontend code I don't see a reason why the query should fail, Sandro, can you please reproduce somehow and attach and Engine log as well?
It seems like the exception should pop around the new/edit VM dialog in the instance images part of the dialog
--- Additional comment from Allon Mureinik on 2016-08-08 06:35:06 EDT ---
The error seems like a user portal widget is attempting to call an admin query. Has anything changed there in the recent future?
--- Additional comment from Tal Nisan on 2016-08-08 09:09:19 EDT ---
Not that I recall, tried to do some actions around that area to trigger something but didn't manage to reproduce and as I mentioned looking around the frontend code I didn't see any query that should fail.
Best course of action is to get the Engine log since the frontend failure doesn't list which exact query failed.
--- Additional comment from Sandro Bonazzola on 2016-08-09 03:21:47 EDT ---
Steps to reproduce:
Access User Portal with admin@internal user
Go to extended tab
Go to new VM
You'll see Instance images enabled with both Attach and Create buttons enabled even if no datacenter is active.
Hit Attach -> exception raised.

org.ovirt.engine.ui.uicommonweb.models.vms.InstanceImageLineModel.$attachDisk(InstanceImageLineModel.java:169) Assuming it is storage. --- Additional comment from Tal Nisan on 2016-08-08 06:09:30 EDT --- Looking at the frontend code I don't see a reason why the query should fail, Sandro, can you please reproduce somehow and attach and Engine log as well? It seems like the exception should pop around the new/edit VM dialog in the instance images part of the dialog --- Additional comment from Allon Mureinik on 2016-08-08 06:35:06 EDT --- The error seems like a user portal widget is attempting to call an admin query. Has anything changed there in the recent future? --- Additional comment from Tal Nisan on 2016-08-08 09:09:19 EDT --- Not that I recall, tried to do some actions around that area to trigger something but didn't manage to reproduce and as I mentioned looking around the frontend code I didn't see any query that should fail. Best course of action is to get the Engine log since the frontend failure doesn't list which exact query failed. --- Additional comment from Sandro Bonazzola on 2016-08-09 03:21:47 EDT --- Steps to reproduce: Access User Portal with admin@internal user Go to extended tab Go to new VM You'll see Instance images enabled with both Attach and Create buttons enabled even if no datacenter is active. Hit Attach -> exception raised.
