In Red Hat Enterprise Virtualization, why tag is not getting detach from resource ?

Issue

• In nested tag, only first two nested tags gets detached/unassigned from any resource.

• Steps to reproduce:

  • Create 3 or more nested tags, for example:

  Root
  -test1
  - - test2
  - - - test3
  

  • Click to VM and Assign Tags button and assign all of these 3 tags to VM (or host)
  • From event log all 3 tags will get attach(test1, test2, test3).
  • Click to Assign Tags again and DETACH all 3 tags from VM.
  • From event log ONLY test1 AND test2 tags will get detach(not test3).
  • Try to detach tag test3 - it's impossible.
