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

Maybe your application is accessing the "members" property when the

Try to turn on logging and see what happens. Add a log statement in
your "members" property getter to be sure.
Did this. The getter is never called, only the setter. This
application is using Spring 1.x for some AOP logging, could it be
manipulating some bytecode somehow to make iBATIS think it needs to
load
the data?

What all would you like to see? It's a large application and the
example I posted is just a snippet. Here's more from my sql config
and dao config:
<sqlMapConfig>
<properties resource="org/projectFoundry/config/
jdbc.properties"/>
<settings enhancementEnabled="true"/>
<transactionManager type="JDBC">
<dataSource type="SIMPLE">
<property name="JDBC.Driver" value="${JDBC.Driver}"/>
<property name="JDBC.ConnectionURL" value="$
{JDBC.ConnectionURL}"/>
<property name="JDBC.Username" value="$
{JDBC.Username}"/>
<property name="JDBC.Password" value="$
{JDBC.Password}"/>
</dataSource>
</transactionManager>
<sqlMap resource="org/projectFoundry/persistence/project/
ProjectSqlMap.xml"/>
<sqlMap resource="org/projectFoundry/persistence/user/
UserSqlMap.xml"/>
etc.
</sqlMapConfig>
<daoConfig>
<context>
<transactionManager type="SQLMAP">
<property name="SqlMapConfigResource" value="org/
projectFoundry/config/sql-map.xml"/>
</transactionManager>
<dao
interface="org.projectFoundry.persistence.project.ProjectDao"
implementation="org.projectFoundry.persistence.project.ProjectSqlMapD

<dao interface="org.projectFoundry.persistence.user.UserDao"

etc.
</context>
</daoConfig>

Subject: lazy loading confusion
Hi All,
I have a Project class with a list of Members. It is my
understanding
that I can turn on lazy loading in my sql map config, define a
Project
result map like:
<resultMap id="result" class="foo.Project">
<result property="projectId" column="id"/>
<result property="members" column="id"
select="Member.listByProject"/>
</resultMap>
and then retrieve a project and the members will not be retrieved
unless I call getMembers() on the project instance. Is this how
it's
supposed to work? What I'm finding is that the members list is
populated even if I do not call getMembers(). To back this idea I
renamed the property in the result map to "members2" and added a new
members2 attribute to the project class (To make sure I didn't miss
any calls to getMembers) and sure enough it is still populated
when I
retrieve the project.
What gives? I thought the point of lazy loading was to not load
data
unless I ask for it. I'm using iBATIS 2.1.7 for Java.
Best Regards,
Tom Duffey
