* Virtual Machines -> select VM -> Disks -> Add -> mark Attach Disk -> don't select a disk -> click OK
* The dialog doesn't close, but no yellow frame or tooltip are shown, and there is no indication of what the user did wrong.
tested on sf10
when pressing ok after reselecting the disk it appears as if the command is sent to the engine and the dialogue is stuck on sand clock forever (until we manually close it)
moving back to devel
Checked on RHEVM 3.2 - SF13:
When user tries to press 'ok' without selecting a disk, a yellow frame appears.
3.2 has been released
