> Тhe default implementation of the ObjectSupplier interface is not capable of creating inner classes and attaching them to an already created parent instance. For example, suppose we have the following class hierarchy:
> class Parent {
>   String name;
>   get/setName() { .. }
>  
>   class Inner {
>       String innerName;
>    }
> }
> Transformed into XML, thiis should look sth. like:
> <Parent>
>    <name>ParentName</name>
>    <Inner>
>        <innerName>InnerName</innerName>
>    </Inner>
> </Parent>
> When ADB is parsing this, it will first invoke the ObjectSupplier requesting an instance of Parent.class, the created instance will be populated, setting its
> name to "ParentName".
> Then, ADB will proceed to create the Inner class instance, however now it will not use the already created Parent, but will create a new one (see DefaultObjectSupplier#getObject(..)). Thus the Inner class instance will have an internal reference to a newly initialized Parent instance, rather than to the already initialized and populated Parent instance. This means that the Inner class will see the Parent's name field as null, instead as "ParentName".
> A possible, but not backward compatible solution would be to extend the ObjectSupplier interface (or create a new interface) adding a new method:
> public Object getObject(Object parentObj, Class clazz)
> The method should use the provided parentObj instance if the given "clazz" is an inner class and "parentObj" is an instance of its enclosing class.
> The other change would be to modify the ADB BeanUtil and pass the corresponding parent instance on each call to the ObjectSupplier.
> If this solution is acceptable, I could provide a patch.
