Comment 3 sefi litmanovich 2017-02-20 13:44:19 UTC

Verified with rhevm-4.0.7.1-0.1.el7ev.noarch according to steps in orignial bug's comment# 55

- Steps to reproduce:
 - create a VM with a disk
 - create a template from this VM, call it T1
 - create a pool from T1 and set it to be based on the latest version of it
 - create a new VM with a disk
 - create a template from this new VM and make it a subversion of T1
 - go to edit pool dialog and change the template version to the base version
 - click OK

Pool edit was successful and no gwt errors were raised.
