hi..

assume i have the following domain classes;

region which has a set of
Country which has a set of 
Location 

while although each one has different set of properties, all implement a 
common interface of 
Node<T extends Serializable >{

Public T getId(); // Region has long id, while Country has String id

public String getName(); // they all have a name to present them

public Collection<? extends NodeModel<? extends Serializable> getChildren() 
// must have wild card for different types of children.

}
now assume i wanted to have a RequestFactory method to get all the regions, 
but get them as NodeModel not as regions, so i would have a client code 
traverse through them like a tree...
problems is i understand i cannot use proxies for domains who have Generics 
in their methods signatures becouse RequestFactory can't validate them .
