Hello!
Thank you very much for implementing the feature to persist the GMF
diagram to a database.
But certainly I am not able to manage it.
A followed the tutorial on elver.org, but I get the following exception
when the save method of the resource gets called:
835872 [main] ERROR org.eclipse.emf.teneo.hibernate.HbMapperException -
Exception when saving resource odm_jobplan

Here some more trace back:

"visible", "type", "element_type", "element_id", "name",

'Diagram', ?)

Persisting my on model "Jobplan" works fine, but persisting the "Diagram"
doesn't work :(!
Thank you very any help!
Best regards,
Matthias
