Collections, cascade, subclasses

hi!

I have a collection of polymorph objects mapped like this:

Code:

<bag name="authInstruments"
   cascade="all-delete-orphan"
   inverse="true"
   lazy="true"
   access="field"
>
   <key column="userId"/>
   <one-to-many class="com.netvisor.uma.persistence.AuthInstrument"/>
</bag>

I have several subclasses of AuthInstruments.

If I add subclasses to the above collection and update the object holding this collection, then only AuthInstruments are saved i.e. only the base classes not the subclasses. This can clearly be seen by the discriminator value...

This is with the Hibernate3 CVS version, but I think it's the same with the old branch...

Am I doing anything wrong? Any ideas? Thanks in advance.

No reply here, seems like I'm the only one with this issue...

Will try ro create a JIRA request and see if that helps.

any hints? it wasn't too useful...

say that RTFM, or will not implement, or already planned, JIRA is replaced by XYZ, etc...

note: i've checked the faq, searched the current manual, forums... i couldn't read about collections + polymorphism anywhere. could be my fault, tough.

Hibernate3 CVS is not even alpha, so it makes not much sense to report bugs. We will have a new JIRA project for Hibernate3 once the alpha is out.

Thanks for the longer description. IIRC I tried with the old branch, and it behaved the same... unfortunately I can't say for sure, because it's a pain to keep up two branches of my code, so i've left the old one behind.

Will get back to it when there's an official alpha/beta version out.
