You mean you now have ArrayListArrayList, as opposed to the array
mentioned in your first post ?
ArrayListArrayList is not a supported property type. ArrayList is.
You could obviously add a dummy class (e.g MyTempClass) as persistable
with the other ArrayList in it as a field so the original

One way to do this would be to duplicate A.name on the associated Bs.
class A {
Long id;
String name;
...
}
class B {
Long id;
Long Aid;
Long Aname;
...
}
Then you'd be able to do your select on just the B entity group and it
would work.

How about something like this?

Then inserting a card into the deck is a simple insert and finding all

This is NOT just a problem with Spring -- stop talking like
optimization is going to fix things. It takes too much time for a
naked servlet to load (i.e; 5-10 seconds). The only jars that I have

Hey,
I presume setMethod() refers to a getter/setter. So, your persisted
class would look like:
@Persistent
Text text;
public void setText(String s) {
this.text = new Text(s);
}
public String getText() {
return this.text.getValue()
}

Thanks for the report David, this certainly seems suspicious. There is at
least one memory leak I'm aware of but it's related to transactions so
that's probably not what you're bumping into. Have you tried taking a heap

There have been numerous posts on the subject of a
NullPointerException popping up when the DataNucleus Enhancer runs. At
one point, I was able to make this problem go away, and now, it is
AGAIN preventing me from running my project.
I've seen about 5 different explanations for what's happening.
removing all of the jars from my user-defined library for gdata and
including only those that i need (core, client, calendar) seemed to
fix the problem.
i remember reading somewhere about how long classpaths can cause this
problem.
is this going to be fixed? is the complexity of my app going to
