ModulDB

when updating a Modul entry and only the text-fields or some other table fields are modified, Doctrine issues queries like:

    UPDATE modules_required SET required_id = ? WHERE module_id = ? AND required_id = ? - (19, 19, 5) 

The parameters in this queries vary, but follow the pattern (x,x,y) and are totaly unrelated to the current modified module.
This leads to self-referencing entries in modules_required and because more than one of this queries is issued leads to a contraint violation in the database.
