I use a combined Primary Key for a User's Phonenumber entity (to match our existing DB model). The key is combined from a "Type" field and a "userId" field that references the User table.
To mark the (referenced!) userId field and the type field as PK, I need to add "userId" to the model (adding @Id to User does not work). This works well when generating Users and Phonenumbers - but the delete command breaks:
PHP Warning: array_combine(): Both parameters should have an equal number of elements in ..../lib/Doctrine/ORM/Persisters/StandardEntityPersister.php on line 274
PHP Catchable fatal error: Argument 2 passed to Doctrine\DBAL\Connection::delete() must be an array, boolean given, called in ..../lib/Doctrine/ORM/Persisters/StandardEntityPersister.php on line 275 and defined in ..../lib/Doctrine/DBAL/Connection.php on line 372
