> Using the event listeners(pre-update,pre-insert) in hibernate,  a problem occurs when validating a lazy collection of composite-elements.
> I was using the @Size validator, but I'm sure others will cause the same problem.
> For example:
>     <set name="activatedModules"
>           lazy="true"
>           table="location_module_activation">
>            <key column="location_id" />
>           <composite-element class="com.opterus.opscenter.model.module.ActivatedModule" >   
>              <property name="activationDate" column="activate_date" not-null="true" />
>              <many-to-one name="module" class="com.opterus.opscenter.model.module.Module" column="module_id" not-null="true" unique="false" />
>           </composite-element>
>        </set>  
> will cause an exception during flush:
> 01:53:55,587 ERROR [http-8080-Processor23] AssertionFailure:22 - an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)
> org.hibernate.AssertionFailure: collection [com.opterus.opscenter.model.common.Brand.regions] was not processed by flush()
>    at org.hibernate.engine.CollectionEntry.postFlush(CollectionEntry.java:205)
>    at org.hibernate.event.def.AbstractFlushingEventListener.postFlush(AbstractFlushingEventListener.java:333)
>    at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:28) 
> Since it tries to access the proxied collection.  A collection of entity objects does not cause this problem.
> I guess the composite-element is handled differently than regular collections?
