I think we have a language barrier issue! :-)
In any case...
References are currently supported as follows:
1. A reference must be made using an attribute <-- important!!!
2. An identity is an attribute (or element that only contains a value)
Assume I have a bar object with ID = 123, and a foo object that
references
the bar... such as:
<root>
<bar id="123">
...
</bar>
<foo bar="123">
...
</foo>
</root>
3. The referencing object must have the appropriate setters and getters:
public class Foo {
public Bar getBar();
public void setBar(Bar bar);
}
4. When marshalling a reference object it appears as an attribute just
like the above example:
<foo bar="123">
...
</foo>
Not as an element: <-- Important
<foo>
<bar id="123"/>
</foo>
In order to support the latter, we need to support container
elements, and
we do not currently support container elements.
5. The mapping file must be as follows:
<class name="Bar" identity="id">
...
<field name="id" type="string"/>
...
</class>
<class name="Foo">
...
<field name="bar" type="Bar">
<bind-xml node="attribute" reference="true"/>
</field>
...
</class>
You cannot use node="element", because we do not support
container-elements yet.
Below in your example you try to use node="element" because you want:
> - <MyAuftrag AuftragOID="1019738737354"/>
This is NOT supported as a reference, but we do support the following:
> <Auftragsposition AuftragspositionOID="1019738737353" MyAuftrag="1019738737354">
Notice that the MyAuftrag is an attribute, not an element. It will be
resolved into the proper MyAuftrag object.
As I've said in a number of postings in the past...references are
currently handled via attributes not elements.
It's basically very similar to ID/IDREF in a DTD...it's all done via
attributes.
My test cases are working properly...so I know it works!
I hope that clears it up.
