@PostLoad invoked before eagerly loaded property finishes lo

[jluv]

I have an entity which has a Map set to load eagerly. When trying to access the map in a method annotated as PostLoad, I am getting a LazyInitializationException ("illegal access to loading collection") from AbstractPersistentCollection.java:341

/**
 * Initialize the collection, if possible, wrapping any exceptions
 * in a runtime exception
 * @param writing currently obsolete
 * @throws LazyInitializationException if we cannot initialize
 */
 protected final void initialize(boolean writing) {
 if (!initialized) {
 if (initializing) {
 throw new LazyInitializationException("illegal access to loading collection");
 }
 throwLazyInitializationExceptionIfNotConnected();
 session.initializeCollection(this, writing);
 }
 }

Correct me if I am wrong, but I think a PostLoad method should not be fired until eagerly loaded properties are finished.

In other words, listeners.onPostLoad(postLoadEvent) from TwoPhaseLoad.initializeEntity shouldn't be invoked until the "initializing" field in each of the entity's eagerly loaded AbstractPersistentCollection objects is set to false.

Any thoughts on whether this should be considered a bug?

How about any ideas for a workaround?

Hi;
I am having the same problem in a Entity postLoad method which access a eagerly loaded Set. Wierd as it doesn't happen on every Load of the entity... :-/

Did you find any sollution on this?

thanks,

[deanouk]

Did either of your find a solution to this? Still having the same problem.

[kindkid]

I'm having the same problem. :/

I see that this issue is also mentioned here:

Anyone find a solution? Thanks a lot.
