Trigger postLoad events and callbacks after associations have been initialized

What do you (Roman and Benjamin) think about adding postHydrate event which would be called within ObjectHydrator::hydrateAllData() on every entity collected during hydration? I could prepare a patch for this. I personally think this would be better than adding a hint that changes behaviour of postLoad event.

Now in my PostLoad access to associations is work fine. Why this issue is still in Unresolved status?

Hi Gyus, I need access to associations in postLoad or similar event, and my idea is to dispatch new event after full initialisation of object, what do You think about it? If I can help please let me know It's important for me.

Moved back

Yes but postLoad has to be triggered for non Hydrated entities (i.e. Persister) also

Leaving that code in UoW does not make sense to me, if it is moved, it needs to be moved completely. Why do you think the persisters should do it? Initially I thought collecting the affected entities during hydration and then when hydration is done iterating over them and triggering the postLoad events.

The query hint would do something like:

        //TODO: These should be invoked later, after hydration, because associations may not yet be loaded here.
        if (isset($class->lifecycleCallbacks[Events::postLoad]) && !isset($hints['hydrationPostLoad'])) {
            $class->invokeLifecycleCallbacks(Events::postLoad, $entity);
        }
        if ($this->evm->hasListeners(Events::postLoad) && !isset($hints['hydrationPostLoad'])) {
            $this->evm->dispatchEvent(Events::postLoad, new LifecycleEventArgs($entity, $this->em));
        }

another way would be to move that code out of UoW::createEntity completly and have the persisters call it when they use that method.

@Benjamin: Not sure what you would use the query hint for but in general that is the approach I had in mind, yes. You can't get around iterating over the entities after the actual hydration.

How would you solve this Roman? I thought of adding a query hint so that the postLoad inside unit of work is not triggered and gathering all the entities that have a post load event in an array inside the object hydrator, then iterating it after taking the snapshots of all collections inside hydrateAll

If this is to be included in 2.0 it needs to happen for RC1. However, it is not clear yet whether it will be done in time.
