for a persistable object, i am getting an integer as a result e.g Object obj = JDOHelper .getObjectId ... for the same object in object db 2.x, i am getting Object obj = JDOHelper .getObjectId(logTestRunImpl) obj ... . Can you please let me know if there is any change in the JDOHelper .getObjectId method from object db 1
