unit tests for PositionRepository::newAction added
unit test for WorkingHoursRepository::createConstraintsFromDemand implemented
unit test for PositionTypeRepository::createConstraintsFromDemand implemented
obsolete method createOrderingsFromDemand removed (is implemented in parent class already)
call to $persistenceManager->persistAll() removed from createAction, use forward instead of redirect in createAction and updateAction.
Persisting manually seems not to be necessary when action is finished.
