I have already delegated post-functions to event listeners. And now I want to delegate workflow validation to my plugin too. How can I do this?
I know that I can create custim workflow validator but in this case Ialso need to assign this validator on the specific workflow transition. Moreover, this validator will be able from validators list but I don't need it. My validator is useless outside my plugin. I need make my validator inaccessible outside plugin.
Thanks.
