OHHHH thanks that was the problem I was using the same pm... It was declarec as field, I changed the method: @Override public List<?> getClientData(MyPersistance filterClass) { // TODO Auto-generated method stub PersistenceManager pm = getPersistenceManagerFactory().getPersistenceManager(); Query clientQ = pm.newQuery(filterClass.getClass()); List<?> clientList = new ArrayList(); List<?> clientPCopy; try { clientList = (List<?>) clientQ.execute(); clientPCopy = (List<?>) pm.detachCopyAll(clientList); } finally { clientQ.closeAll(); } return clientPCopy; }
And now It's Ok... Thanks... -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
