Validating a lazy collection of composite-elements causes flush problem ------------------------------------------------------------------------ Key: HV-37 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-37 Project: Hibernate Validator Issue Type: Bug Affects Versions: 3.0.0.ga Environment: Hibernate 3.2.4ga Hibernate Annotations 3.3.0.ga mysql 5.0.27 Reporter: Ian Long 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?
