That would require change of my data model. I am using castor to allow
different application with diffrent data model communicate with each. Changing
my model would create a coupling again.
It seems to be possible to grab a parent id and list of children and create a
proxy object (of course if it would work, I wouldn't have this problem). It
seems like I am missing something in logic of nested class. How can I debug
this
<field name='foo'>
<bind-xml name='Foo'>
<class name='MyMap'>
<field name='id' type='int'>
<bind-xml name='id' node='attribute' />
</field>
<field name='childName' type='java.lang.String'>
<bind-xml name='name' node='attribute' />
</field>
</class>
</bind-xml>
</field>

Hi Farhad Ch,
as far as I can tell this isn't possible as long as the child does not
know its parent. If you add such a reference you have 2 possibilities:
- add getter and setter methods for the parents property at the child
- try to add a field mapping for 'parent.id' at class mapping of child
Regards
Ralf
