Forbid Sub-task creation on certain statuses

Question

Hi all,

I would like to ask if there is a possibility to forbid subtask creation for users when the issue is in certain Status. e.g. Status is "Open" and nobody can create sub-task until status is not changed.

thank you in advance

One solution is described here:

or use the parents status validator of JIRA Misc Workflow Extension (use it in the create transition of your subtask workflow)
