my bad.. my stupid programming style I guess....
I changed from
PersistenceManager pm = ...getPersistenceManager();
try {
return pm.getObjectById(MyModel.class, id);
} finally {
pm.close();
}
to
PersistenceManager pm = ...getPersistenceManager();
try {
MyModel m = pm.getObjectById(MyModel.class, id);
return pm.detachCopy(m);
} finally {
pm.close();
}
and still it didn't work. and then I changed to
PersistenceManager pm = ...getPersistenceManager();
MyModel m = null, detached = null;
try {
m = pm.getObjectById(MyModel.class, id);
detached = pm.detachCopy(m);
} finally {
pm.close();
}
return detached;
and hurray!!! it works now.. Thanks anyways...
Anybody know why?
