Essentially the issue outlined here: http://stackoverflow.com/questions/8748785/symfony2-collection-form-does-not-fill-join-column

Expected outcome:

When adding new collection items using a collection form field, the owner of the collection items is set.

Actual outcome:

The owner of the collection items is not set.

Steps to reproduce:

1. Create two entities with a one-to-many association (i.e. Office(id) ----< Contact(id)) - enable cascading persists on office.contact.
2. Create form types for the two entities, setting office.contact as a collection form field and the necessary actions & template.
3. Add a Contact using the form and save it in the action.
4. The resulting Contact will have a NULL office_id.

The workaround is to manually iterate over office.contacts and set the office on them.
