JDOUserException while initializing datastore [message #76225]

Hello,

I'm new to Teneo and this newsgroup...so I hope this is the right place to
ask my question.

I used Teneo to create a package.jdo-File from my ecore-Model. This worked
fine...After this I created a JpoxDatastore and tried to initialize the
database. Now I'm running in a JDOUserException in a specific class.

Here's the exception-message:

javax.jdo.JDOUserException: Specified field
"StructuredActivityNodeImpl.in" has no container (collection/map/array)
MetaData!

Here's the mapping for this class:

<class name="StructuredActivityNodeImpl" requires-extent="true"
persistence-modifier="persistence-capable" detachable="true"
identity-type="datastore">
<implements name="StructuredActivityNode"/>
<inheritance strategy="superclass-table">
<discriminator value="StructuredActivityNode"/>
</inheritance>
<version strategy="version-number" column="e_version"/>
</class>

(There is no class-tag for my StructuredActivityNode-class)

I don't know what is wrong here...
So, my question is, if this could be a bug in the generation-mechanism of
Teneo, or is there something I have to do?

Regards.

Hi,
Can you post/attach the complete ecore (and the package.jdo)? You can also send the ecore directly
to me if you don't want it posted on a public newsgroup.
Which version of emf/teneo are you using?

Hi!

Thanks for your reply. I would prefer to send the package.jdo and the
ecore file per email, since I did not write the ecore-file myself. I found
your email-address on the elver-site. Is that the correct one?

Regards

Hi,
Yes that's the correct one. It will probably be later today before I can look at it further.

A question I forgot to ask, did you put the package.jdo file in the generated java source tree and
was copied by eclipse to the classes/bin/output directory?

Hi,
Your model has multiple inheritance. The support of jpox for multiple inheritance is less advanced
than with teneo/hibernate. Based on your model I have started to solve this for jpox also (and
solving some remaining issues with Hibernate multiple inheritance). Probably after the weekend I
will have solved this and do a new release.
Can you enter a bugzilla for this? Then I can report the progress in that bugzilla. Thanks.

Hi!

That's great!

Thank's a lot for the support!

I'm looking forward for the new release!

I've just created a new bugzilla under number 179084, hopefully I did it
correct.

Best regards
Markus Bischof
