Did you by some chance miss to "double bind" entities. That is, you need to do for example:

$forum = .... // some forum
$thread = .... // new thread;

$forum->getThreads()->add($thread); // first add to list
$thread->setForum($forum); // but also set forum parent within `Thread`

and then persist entities as usual...
