Hi Nebulus,
Indeed objects loaded from the database have the hibernatepersistableelist and new objects have an EMF elist. However,
this normally works fine. So afaics this is not the problem. I guess you don't see exceptions etc.?
Apart from this the only thing you can do is debug some more into the HibernateResource (in the method taking care of
saving to the database)?
Then when you have more info just post it on the EMF newsgroup and I can take a further look.
Teneo is supported on the EMF newsgroup which I added as cc.
gr. Martin
