Subject Re: CForms binding usage
Date Mon, 07 Mar 2005 22:33:12 GMT

    Thanks very much for the response.  What I'm looking for is an 
alternative to manually calling the setters (and getters for populating 
the form object) of my business object for each Form field value.  
Imagine Hibernate for Form Object to Business Object relationships.  I 
don't want the from directly tied to the database even though the 
documentation show you can do just that.  It sounds like that's what the 
Form Binding gives me.

    So in review, I should be able to do the following:

Form Definition:



    <fd:field id="name">
      <fd:label>Bean Name:</fd:label>
      <fd:datatype base="string" />
        <fd:length max="100" />




    public class MyBean {

        private String name;

        public void setName(String name) {
  = name;


    var myBean = new MyBean();
    var myForm = new Form("add-new-MyBean-form-template.xml");


And have the myBean variable's name field populated, does that sound right?
