Hi,
I'm having trouble updating a class which has an array of ints:
@PersistenceCapable
class Foo {
@Persistent
@Extension(vendorName = "datanucleus", key = "gae.unindexed",
value="true")
int[] vals;
}
...
Foo foo = new Foo();
foo.vals = new int[] { 1, 2, 3 };
pm.makePersistent(foo);
The first time an instance is created, the values are all there ok. If
I try updating them though, the changes never persist:
public void updateFoo(PersistenceManagerFactory pmf) {
PersistenceManager pm = pmf.getPersistenceManager();
Foo foo = pm.getObjectById(Foo.class, myKey);
foo.vals[0] = 100;
pm.makePersistent(foo);
}
I print the values out directly after the call on the foo object
instance, and the update seems to have worked in memory. However, the
next time I call updateFoo(), the values are once again starting at
{ 1, 2, 3 }, and not { 100, 2, 3 } as I'm expecting. What am I doing
wrong?
Thanks
