JDOUserException while initializing datastore [message #603782] Thu, 22 March 2007 10:31

I'm new to Teneo and this 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
"" has no container (collection/map/array)

Here's the mapping for this class:

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

(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?
