No it can't - it should only be invoked once per object.
As far as I can tell in the debugger setPersistanceState(state=NEW) is being
invoked multiple times..
First when I create the object and then later on when I commit(there are
child contexts involved, and I first commit to parent, then to the
database):
if (dataObject.getObjectId() == null) {
dataObject.setObjectId(new ObjectId(objEntity.getName())); //
DataContext.registerNewObject(DataObject) line: 920
}
