Description Tomas Jelinek 2016-01-07 10:15:39 UTC 
There is a race condition in the basic and power user portal. In slower environments if there are both VMs and pools, if the run VM is executed, a NPE is thrown.

It does not do too much damage since it happens only after the command has been sent to server, but the popup with unhandled exception is shown anyway.

Reproduce:
1: have an engine server which is running for some reason quite slow (e.g. slow network between frontend and backend or the engine machine is loaded or something). If the queries return fast it will not reproduce
2: have both VMs and pools
3: click "run" on any VM
4: there is an exception thrown
