* administrator has selected, and populate the other association fields with these records. (Otherwise, if the
* administrator just clicks on Save without clicking on Propagate, those other associations will be deleted).

* to the server to find the other associations, also passing up the language of the record currently being edited,
* as it should be excluded.
* Once it has received from the server the other associations it calls injectAssociations to inject them into
