Hi, I think it is a bug around transaction of JDO/SDK1.3.1.
It does not occurs with SDK1.3.0
----
Entity entityA = pm.getObjectById(Entity.class, "keyA");
entityA.setDoubleProperty(Math.random());
tx = pm.currentTransaction();
tx.begin();
// This makePersistent throws "javax.jdo.JDOException:
// can't operate on multiple entity groups in a single
// transaction.", if any properties of the entity gotten
// via getObjectById was updated.
pm.makePersistent(new Entity("keyB"));
if(tx.isActive()) tx.commit();
