This can occur when you assign an existing id to a new instance, and before flushing attempt to load the existing instance for that id. > FailedObject: at.ac.tuwien.tiss.curriculum.be.entities.DefaultCourse-26301 > at org.apache.openjpa.kernel.ManagedCache.add(ManagedCache.java:126) > at org.apache.openjpa.kernel.BrokerImpl.setStateManager(BrokerImpl.java:4117) > at org.apache.openjpa.kernel.StateManagerImpl.initialize(StateManagerImpl.java:391) > at org.apache.openjpa.kernel.StateManagerImpl.initialize(StateManagerImpl.java:340) > at org.apache.openjpa.jdbc.kernel.JDBCStoreManager.initializeState(JDBCStoreManager.java:378) > It seems that this entity gets loaded from the db twice in the same query. > While hitting the problem, the StateManagers have the following _flags: > orig _flags= 602 = 0010 0101 1010 SAVE LOADED READ_LOCKED OID_ASSIGNED FLUSHED > sm _flags= 16 = 0000 0001 0000 READ_LOCKED > And it is really only 1 instance which makes this problem. If I set the 'orig' variable to null in the debugger, the test runs fine. -- This message is automatically generated by JIRA.
