Wrong package name generated by hbm2java for a sub-subclass

Hibernate version: Hibernate 3.1.2
Hibernate-tools version: hibernate-tools-3.1.0.beta4

Hi List,
I'm experiencing a somewhat weird behaviour of hbm2java when mapping the following class hierarchy:

Code:

AbstractExampleEvent <-- ExampleEvent <-- ExampleSportsEvent

using the attached mapping.

The generated class for "ExampleSportsEvent" (using the meta "generated-class" tag) which is mapped as a subclass of "ExampleEvent" is generated with a ridiculous package name of:

Code:

ch.unartig.studioserver.model.GeneratedExampleEventch.unartig.studioserver.model.GeneratedExampleSportsEventch.unartig.studioserver.model

instead of just:

Code:

ch.unartig.studioserver.model

The problem only occurs for the sub-subclass mapping.

Creating (or renaming) the abstract classes manually everything seems to be fine with the posted mapping. Am I missing something?

Thanks a lot,
Alex

you should put inherit="false" on all "generated-class" attributes.

... of course. Thanks a lot, Max, for that quick hint.
