No, it's not clear to me once again, sorry, but the above suggestion does not
fit the real case.
Let's make a more concrete example.
class Person
{
String firstname;
String lastname;
}
class PhoneNumber
{
Person person;
String dial;
boolean mobile;
}
class PersonFormComponent extends FormComponent<Person>
{
PersonFormComponent(Person p)
{
super("personFormComponent", new CompoundPropertyModel(p));
add(new TextField("firstname"));
add(new TextField("lastname"));
}
}
class PhoneNumberComponent extends FormComponentModel<PhoneNumber>
{
PhoneNumberComponent(PhoneNumber n)
{
super("phoneNumberFormComponent", new CompoundPropertyModel(n));
add(new TextField("dial"));
add(new CheckBox("mobile"));
}
}
class PersonForm
{
PersonForm(Person p)
{
super("personForm");
add(new PersonFormComponent("personFormComponent",
new CompoundPropertyModel(model));
PhoneNumber pn = findOrCreatePhoneNumber(p);
add(new PhoneNumberFormComponent("phoneNumberComponent", pn);
}
}
PersonForm.html:
<form wicket:id="personForm">
First Name:<input type="text" size="20" wicket:id="????"/>
Last Name:<input type="text" size="20" wicket:id="????"/>
...
Phone Number:<input type="text" size="20" wicket:id="????" />
Mobile?<input type="checkbox" wicket:id="????" />
</form>
What should I write in place of "????" ? If I put the FormComponents IDs then
the CompoundPropertyModels won't find the fields to bind. If I put the beans
fields names, then the PersonForm constructor won't find the IDs to bind the
whole FormComponent subclasses.
Can you please show me the markup needed for the above example?
