When i try to change the transition by clicking on status, it just spins and nothing happens.
I right click on status, open in a new tab and from there I can change the status.
This transition has validation which uses workflow toolbar plugin and without this validation it works fine.
I dont see any entries in logs also.
Jira version --> 6.4.3 Plugin version --> 2.2.1
Let me know if you need any information from my side.
