Interraction with other modules

Greetings!
I've got a small module called comment_join here on drupal.
It does a simple thing - whenever somebody posts a comment right after another comment of his, the comments get merged.

And now it looks like things do not go well if both yours and mine modules are on.

http://drupal.org/node/1234988

What happens now is that
1) ajax_comments submits a new comment
2) comment_join removes the new one and adds it to the old one
3) ajax_comment sees that there is no new comment and does not even refresh anything...

And the problem is that comment_join works server-side and has no knowledge of the form the user is working with.

What do you think could be done at this point? Could possible ajax_comments run a page refresh if no comment appeared at this point?

Thank you!
