[CForms] Creating an intermediate object in binding

[Ugo Cei]

Let's assume I have a Person class:

public class Person {
  public String getFirstname();
  public String getLastname();
  public Address getAddress();
  ...
}
and an Address class:

public class Address {
  public String getStreet();
  public String getTown();
  ...
}

I am building a form interface for editing a Person, with this binding:

<fb:value id="street" path="address/street"/>

Now, when trying to save the form, JXPath will do a  
jxpathContext.createPathAndSetValue which will fail because  
person.getAddress() is null and the JXPath context doesn't know how to  
create an Address.

I could work around this problem by making sure person.address is not  
null before loading it into the form, but I don't like this solution. A  
better option, maybe, would be setting a factory on the context, like  
is shown here:  
http://jakarta.apache.org/commons/jxpath/users- 
guide.html#Creating%20Objects

My problem is: where do I set this factory in CForms, assuming this is  
possible at all?

        Thanks in Advance,

                Ugo
