What is the type of your
"members" property.
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.

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.
