I'm looking for a way to prevent an issue to go through a transition, when there is another issue with a blocking link on the same (or previous in workflow) status. I know there are certain plugins that would allow you to do this on a self-hosted instance, but how about OnDemand. I can't seem to find a way. Anyone?
As a bonus question, how about more than one level of sub-tasks. Doable?
Thanks
Andreas
