Dennis Sosnoski reassigned JIBX-36:
-----------------------------------
Assign To: Dennis Sosnoski
> Custom unmarshallar unmarshal method always gets passed null object reference
> -----------------------------------------------------------------------------
>
> Key: JIBX-36
> URL: http://jira.codehaus.org/browse/JIBX-36
> Project: JiBX
> Type: Bug
> Components: core
> Versions: 1.0-beta3c
> Reporter: Thomas Jones-Low
> Assignee: Dennis Sosnoski
> Fix For: CVS
>
>
> When writing a custom unmarshaller the initial call to
> IUnmarshaller.unmarshal() alwasy has a null object refererence. This is a
> problem when the object has been instatiated by the constructor of the
> enclosing object.
> For example:
> The class file:
> public class Notation {
> private string name;
> private HTMLDocument notation;
> public Notation {
> notation = new HTMLDocument();
> }
> }
> The Binding file:
> <binding>
> <mapping class="javax.swing.text.html.HTMLDocument" name="comment"
> marshaller="HTMLListMapper"
> unmarshaller="HTMLListMapper">
> </mapping>
> <mapping name="notation" class="Notation">
> <value name="name" field="name"/>
> <structure field="comment" usage="optional"/>
> </mapping>
> </binding>
> public class HTMLListMapper implements IMarshaller, IUnmarshaller, IAliasable
> {
> public Object unmarshal(Object obj, IUnmarshallingContext ictx);
> }
> When HTMLListMapper.unmarshal() gets called, obj is null and the unmarshal
> method is expected to create the HTMLDocument. What should happen in the
> HTMLDocument reference from the Notation class should be passed instead.
