Since we are using an IN() query for this we can only support this feature for entities that have a single column primary key.<br/> 2. If we want to support composite keys we need to build it as WHERE ( (id1 = ? AND id2 = ?) OR (id1 = ? AND id2 = ?)) but this is currently not possible with the way how internally the $criteria array is used.</p> <p>Next item to think about: What if an exception or event breaks the flow and "triggerEagerLoads()" is never called?</p> DDC-733 DDC-734 DDC-53 DDC-914 DDC-1060 DDC-963 DDC-865
