I'm using the latest from iBatis, which I compiled myself from svn last
week. I'm using Spring 2.0 rc4 and I have both enhancementEnabled and
lazyLoadingEnabled set to true, and I am experiencing no problems. Lazy loading
is working as expected. Here's the snippet from my
sql-map-config.
<settings
cacheModelsEnabled="true"
errorTracingEnabled="true"
enhancementEnabled="true"
lazyLoadingEnabled="true"
maxSessions="250"
maxTransactions="30"
maxRequests="500"
useStatementNamespaces="true"/>
cacheModelsEnabled="true"
errorTracingEnabled="true"
enhancementEnabled="true"
lazyLoadingEnabled="true"
maxSessions="250"
maxTransactions="30"
maxRequests="500"
useStatementNamespaces="true"/>

doubt this would change anything.
I'm not using Spring, but if this sort of problem is normal with Spring,
the mailing list would already contain a solution.
Can anyone confirm that lazy loading works with Spring?
If so, then maybe it is the Spring configuration that is problematic.

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