How do you allow a parent CR to not progress to the next transition until all CR-Subtasks have been closed? I need the button to be visible but throw an error message when clicked.

There's two questions here, sort of.

1. To prevent a parent from moving on while it's got open subtasks, the standard approach is to use the "subtask status blocking" condition. That lets you set conditions on a workflow like "only show this transition if all the subtasks are in status X, Y or Z"

2. Answer 1 above works, but does not meet your "visible/error message" criteria. In Jira, a "condition" stops a user from seeing the option to try a transition. What you're asking for is a "validator" - these don't stop a user seeing or starting a transition, but stops them completing it if the data is wrong.

I've not seen a plugin that will provide a validator that will look at the subtask-status, so I think you might need to do a bit of coding. Of course, you can "borrow" the code from the condition, it'll be almost identical.

Note - I use the condition, and have never really needed to look for a validator style way to do it, so I don't want to tell you there is nothing out there, just that I've never looked.

Thank you. Would you be able to tell me how I can view the code for the blocking condition?

Ah, the one I use is in Jira off-the-shelf, so it's part of the core code, and that's closed so I can't share it.

If you've got a commercial licence, you can download the source for Jira from your my.atlassian account and find it in there. Shouldn't be hard to extract the condition and convert to a validator.
