I can't see why this doen't work.
Try posting the logs from iBATIS and your sqlMap file
containing Member.listByProject.

Is your User class final?
I don't think so:
public class User extends BaseObject implements java.io.Serializable,
Cloneable
{
...
}
and in Project the association that I'm testing is just:
public class Project extends BaseObject implements
java.io.Serializable
{
...
private User[]
justForTesting = new User[0];
public User[]
getJustForTesting() { return this.justForTesting; }
public void
setJustForTesting(User[] justForTesting) { this.justForTesting = justForTesting;
}
}
Also I have another lazily-loaded association defined with a single User
rather than an array of them which is working fine.

Remember that final objects cannot be lazy
loaded.
If you are using a final object in your "members"
property, iBATIS will definetly load it even in lazy
mode.
I tried User[] (User is one of my
classes) and List.

Try explicitly enabling lazy loading:

It seems
to me I remember some others reporting that it had to be specifically
enabled (even though it is supposed to be enabled by default).
Maybe we have a bug?
Using those settings results
in the same thing. I should mention that I have other lazily-loaded
properties that iBATIS is handling properly. I'm going to try
removing Spring and see if it makes any difference.
Well I'm stumped. I
pulled out Spring and the problem is still happening. Is there any way
for me to get more debugging information from iBATIS about why it thinks it
needs to load the association?

Same thing. I'm using
CGLIB 2.1 which was the oldest version I could
find on their
site.
