Cascade Broken (worked in 3.0.5) -------------------------------- Key: HHH-1504 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1504 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.1.2 Reporter: Michael Kopp Assignee: Gail Badner Attachments: Node.hbm.xml, Parameter.hbm.xml, stacktrace.txt, Transition.hbm.xml, Workflow.hbm.xml The attached Mappings worked perfectly in HB 3.0.5, in 3.1 the save throws org.hibernate.PropertyValueException org.hibernate.PropertyValueException: not-null property references a null or transient value: com.j2fe.workflow.definition.Transition.target I even debugged it and the enity given to org.hibernate.event.def.AbstractSaveEventListener.performSaveOrReplicate (a transition object) contains an object in the 'target'. I have to add that the object in 'target' already contains a generated ID, which means it was already saved. The values array given to the org.hibernate.engine.Nullability.checkNullability does not contain it, which is the cause of the exception, the question is why it was nulled!! the Transition bascically contains a 'source' and a 'target' Node. and a Node contains sets of Target Transitions and Source Transitions. This is a network of objects!! Please Remember that these mappings worked in 3.0.5, I only have this problem after switching to 3.1. I even tried to set cascade to all on every single relation i have in the model and it still produced that error. org.hibernate.PropertyValueException: not-null property references a null or transient value: com.j2fe.workflow.definition.Transition.target at org.hibernate.engine.Nullability.checkNullability(Nullability.java:72) at org.hibernate.event.def.AbstractSaveEventListener.performSaveOrReplicate(AbstractSaveEventListener.java:265) at org.hibernate.event.def.AbstractSaveEventListener.performSave(AbstractSaveEventListener.java:167) at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:114) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:186) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:175) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.performSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:98) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:70) at org.hibernate.impl.SessionImpl.fireSaveOrUpdate(SessionImpl.java:531) at org.hibernate.impl.SessionImpl.saveOrUpdate(SessionImpl.java:523) at org.hibernate.engine.CascadingAction$1.cascade(CascadingAction.java:134) I will attach the full stacktrace in a file as it is rather big.
