Re: [hibernate-dev] [OGM] EntityKey missing methods ?
Because Hibernate raises an exception if you call persist on an already existing entry.

Ok greate, so why the engine calls getTuple when I perform a persist

OGM-40 will add those, it's next on my todo list. But you should not have do read the
DB to know if an object is already there. That's the job of the hibernate engine and
it is reflected in the dialect API. If you are missing something, let me know.
