The parent ticket is not an active ticket (status: closed).

Beacuse no any activity here, I did it myself. Here is the solution, edit the file childtickets/childtickets.py and comment there lines:

# If the parent is 'closed' then we should not be allowed to create a new child ticket against that parent.
#if parent['status'] == 'closed':
#    yield 'parent', "The parent ticket (#%s) is not an active ticket (status: %s)." % (pid,parent['status'])

Rebuild, reinstall ... and now, the plugin is usable.

Hi

The idea here was to prevent child tickets being created against parents that are already closed.

In the development environments I have worked in, we've generally had a rule that tickets should only be worked on in an 'open' state. That would mean re-opening the ticket first (and the parent if that is also closed!). Because this restriction is being tested for in the ITicketManipulator::validate_ticket function, there's no easy way to distinguish between creating a new ticket, simply adding a comment to an already closed ticket or performing some other change to the child ticket ...

I'm glad you got it working and adapted to your environment easily. Perhaps there should be an option here to allow child tickets to be created/modified against closed parent tickets?

Yes. It would be fair enough to have the option to disable this feature. I understand your motivation and it looks fine for me, the only problem is that this restriction influences every change you'd like to perform on child ticket, when the parent ticket is closed (like adding a comment), so (probably because of the trac architecture, as you said) is far too much restrictive.

On the other hand your plugin is really helpful and simple, and I use it on daily basis. Thanks!

BTW. I use for example different workflow, where I don't need the feature above.

I have bigger Feature ticket that can have Task, Bug, Idea subtickets.

So while the Feature is open, usually it has some Tasks attached. When all Tasks are done, the Feature is done. But this shouldn't prevent to still add the Bugs and Ideas below the Feature, and what shouldn't always reopen Feature (it's still done).
