Warren,
Something like this?
public class HomePage extends WebPage {
private List<Vendor> vendors = Arrays.asList(new Vendor("v1"), new
Vendor("v2"));
private Vendor vendor = new Vendor("default vendor");
public HomePage(final PageParameters parameters) {
Form<Void> form = new Form<Void>("form");
add(form);
// use your existing LDM instead of this hard-wired List of vendors
but
// make sure you merge your edits properly!
form.add(new ListChoice<Vendor>("vendors", new
PropertyModel<Vendor>(this, "vendor"), vendors));
Form<Void> editForm = new Form<Void>("vendorEditForm");
add(editForm);
editForm.add(new TextField<Vendor>("name", new
PropertyModel<Vendor>(this, "vendor.name")));
}
private class Vendor implements Serializable{
private String name;
protected Vendor(String name) {this.name = name;}
public String toString(){return name;}
// safer to have accessors & mutators
}
// safer to have accessors & mutators
}
