Hello,
Iam using TENEO framework and tried to update then object using session.merge().But Iam getting below error:
'Entity not Merged: object references an unsaved transient instance - save the transient instance before flushing'.
The object has list of children of same type. Also I have set following two properties during datastore initialization.
props.setProperty(PersistenceOptions.CASCADE_POLICY_ON_CONTAINMENT, "REMOVE,REFRESH,PERSIST,MERGE");
props.setProperty(PersistenceOptions.CASCADE_POLICY_ON_NON_CONTAINMENT, "MERGE,PERSIST,REFRESH,DELETE_ORPHAN");
Thanks
Chandru

Hi Chandre,
Yes with these properties things should be fine normally. The next thing is to debug into hibernate, set a breakpoint
where hibernate throws the exception, check which entity it is and then check the hbm (dataStore.getMappingXML) if
indeed the mapping is correct.
If you don't see any special then can you post the hbm here with info on which entity/association it fails?

Thanks Martin.
Please find the hbm below. Iam getting issues when i try to merge execution with children into db. List of children refers to list of executions.
<subclass name="com.test.ExecutionImpl" entity-name="Execution" abstract="false" lazy="false" extends="PropertyContainer" discriminator-value="Execution">

Hi Chandre,
Okay and the transient instance is an instance of Execution (and the association it uses to get their is the
'children')? I mean this is what your debugging found?
To be sure that I/we are looking at the correct association...
(I ask because the mapping looks fine to me, the merge is part of the cascade settings.., so not sure why it does not work)
