binding form to object without default constructor

[Brad Fritz]

Greetings,

I am new to Wicket and having some trouble binding a Wicket Form
component to an object that does not have a default constructor and
does not follow the javabean pattern.  I have read and re-read the
wiki information on models and checked the mailing list archives but
haven't made much progress so far.  (I am using Wicket 1.3.0.)

My object looks like this:

  public class Foo {

      private Long id1;
      private Long id2;
      private String bar;

      public Foo(Long id1, Long id2) {
          this.id1 = id1;
          this.id2 = id2;
      }

      public Long getId1() { return this.id1; }
      public Long getId2() { return this.id2; }

      public String getBar() { return this.id2; }
      public void setBar(String bar) { this.bar = bar; }
  }

My form will contain RequiredTextField components for id1 and id2 and
a TextField for bar.

Can someone point me in the right direction for binding the form
values to a new instance of Foo?

I would be happy to add an example to the wiki after I figure out the
solution if anyone thinks that would be helpful.

Thanks for any help!
