My advise is to first check if the association is in order (without using the
ZF2 Form component).
You can use the console to validate your mappings:
$ doctrine orm:validate-schema
Then simply try adding/removing TimeTableList-s to/from a User. If that works,
you can proceed to using the Form component.
PS: I suspect the association part is in order, and you're having trouble with
the Form component. I don't have any experience with the ZF2 Form component,
but maybe others here do. I do suggest you post this issue on a ZF2
mailing-list or forum, as it's more of a ZF2 thing than a Doctrine2 thing ;)
