Hi,

I wonder what the exact difference between IObjectTransaction#register() and
#registerNew is? Can anyone give me a hint?

Thanks and greetz

Hi Carsten,

As far as I know the difference is:
- with register() an object is registered that should not be tracked as
a new object
- while registerNew() registers a new object which should be tracked

Tschüß,
Stefan

Like Stefan said,

the difference is the state that the registered object gets. The object transaction keeps a state if the object was
brought in as "new" object or whether it was instantiate new but already existed in your persistentant store.

So later when you extract the Changes then you get the information whether that was an object that was new or existing
in the first place.

hope that helps
