[appengine-java] [JDO/SDK1.3.1] A bug around transaction
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(); - Full source code is here. - http://code.google.com/p/test-gae-j-sdk-131/ Compiled application is deployed on here. - http://test4sdk131.appspot.com/ -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

After that, I changed back to 1.3.0 and re-deploy, then the Exception stopped. (Of course I used the same source code.) So, I think it is a bug of 1.3.1. Or, is it a bug of 1.3.0? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Sorry, I am wrong. I inspected my source code and found the real cause. The following code can works on SDK1.3.0, but it throws java.lang.IllegalArgumentException: can't operate on multiple entity groups in a single transaction. when it used on SDK1.3.1. PersistenceManager pm = pmfInstance.getPersistenceManager(); pm.makePersistent(new EntityB(key)); // If this two lines are commented out, pm.getObjectById(EntityB.class, key); // the following code throws exception on SDK1.3.0 too. ArrayListEntityA entities = new ArrayListEntityA(2); entities.add(new EntityA()); entities.add(new EntityA()); Transaction tx = pm.currentTransaction(); tx.begin(); pm.makePersistentAll(entities); // it throws exception if it compiled using sdk1.3.1. tx.commit(); Full source code is here. https://test-gae-j-sdk-131.googlecode.com/hg/ On 2月12日, 午前3:11, Max Ross (Google) maxr+appeng...@google.com wrote: Assuming a ClassA object with the specified id already exists, the code you've posted works fine for me.

Is it a bug on JDO of SDK 1.3.1? -- PersistentManager pm = PMF.get().getPersistenceManager();; ClassA classA = pm.getObjectById(ClassA.class, id); ClassB classB = new ClassB(); Transaction tx = pm.currentTransaction(); tx.begin(); pm.makePersistent(classB); tx.commit(); // It throws javax.jdo.JDOException: can't operate on multiple entity groups in a single transaction. -- -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
