> Key: JIBX-105
> URL: http://jira.codehaus.org/browse/JIBX-105
> Project: JiBX
> Type: Bug
> Components: core
> Versions: JiBX 1.1, JiBX 1.0.1
> Environment: blackdown-jdk-1.4.2.03

> I have a project where I have a Survey object that contains a Set of Locale
> objects. These are managed by hibernate and the collection is lazy loaded.
> I have the following binding definition:
> <binding>
> <mapping name="survey" class="model.Survey">
> <value name="name" field="name"/>
> <collection name="locales" field="locales"
> factory="model.Survey.hashSetFactory">
> <structure name="locale" type="model.Locale" pre-get="debug">
> <value name="language" field="language"/>
> </structure>
> </collection>
> </mapping>
> </binding>
> I have a JUnit test that attempts to load the Survey object and serialize it
> using JiBX. When it runs here is the output:
> test-module:
> [echo] Testing domain...

> I'm not sure what exactly is going on, but when i disassembled the modified
> Locale.class using Jad v1.5.8e, this is what the
> model.Locale.JiBX_binding_marshal_2_0 method looked like:
> public final void JiBX_binding_marshal_2_0(MarshallingContext arg1)
> throws JiBXException
> {
> debug();
> arg1.pushObject(this);
> arg1.element(0, "language", language);
> arg1.popObject();
> return;
> }
> Somehow its printing out the fields of the Locale object, and then trying to
> add the language field to the MarshallingContext and it becomes null before
> the call to element().
> I have created a project that demonstrates this behavior. I will tar it up
> and attach it.h
