Hide Transition doesn't work as expected

Original Description:

JIRA 6.3 introduced a Hide Transition condition to hide the transition on the GUI but allowing to be called it from another workflow function or program.

However this latter doesn't work. I have 2 plugins that fails to trigger a transition that uses this condition: Jira workflow toolbox and jira automation.

Answer

Indeed the Hide transition from user condition was added in JIRA 6.3.3. This condition will always fail, causing the Transition to never be available to be called manually. This was created in order to extend the usage of Workflow Triggers, in order to make certain transitions only possible through triggers (not manually):

Triggers are events which initiate an automatic workflow transition for a JIRA issue. Examples of triggers are pull request creation, or code review rejection.

Caveats: Conditions, validators, and permissions will be ignored for automatic transitions but operate as usual for manual transitions. Global transitions can be automated with triggers, if you follow some simple guidelines. Read our best practices page on automatic issue transitioning.

Third-party plugins trying to transition an issue will indeed not be able to do so, nor will the REST API work.
