I have problems using Oracle when a objet have a collection of anothers and I make saveOrUpdate().
Basically, I have a worflow wich contain a step collections.
In Oracle, when it wants to save some of the passages of workflow says to me that it is not defined you go of workflow that would go in table WFSTEP (down I put the error) the error just throws it when I make tx.commit(); But the rare thing is that soon of saveOrUpdate(workflow), I logg you go of workflow and I see that exists. In addition if I inspect the object soon workflow of saveOrUpdate(), I see that everything appears ok bony it has the collection of steps and each one with his you go well seted.
Thank's for you attention.
Martin.


Hibernate version:
3.0
Mapping documents:
Workflow.hbm.xml
<bag name="wfSteps" cascade="all" lazy="true" inverse="true">
<key column="NK_WORKFLOWDEFIN" foreign-key="NK_WORKFLOWDEFIN_NK_WSTEP"/>
<one-to-many class="com.sisdam.jcs.workflow.model.WFStep"/>
</bag>

WFStep.hbm.xml

<many-to-one name="workflow" cascade="none" column="NK_WORKFLOWDEFIN" class="com.sisdam.jcs.workflow.model.Workflow" not-null="true" foreign-key="NK_WORKFLOWDEFIN_NK_WSTEP"/>


Code between sessionFactory.openSession() and session.close():
Tablas :
Workflow(idWorflow,name,etc);
WFSTEP(idStep,idWorkflow,etc);

Codigo:
Transaction tx=session.beginTransaction();
session.saveOrUpdate(workflow);
log.debug("HibernateWFPersistenceManager :: saveWorkflow() :: workflow id : " + workflow.getId());
workflow.setId(workflow.getId());
tx.commit();
