In Action code, before forwarding to the JSP, look up the Person
object and pre-populate the form bean's 'name' property.
Is it possible with a dynaActionForm?
Sure.
DynaActionForm dForm = (DynaActionForm) form;
dForm.set( "name", person.getName() );
You can also use BeanUtils to copy properties from the Person to the
Form bean:
BeanUtils.copyProperties( dForm, person );
Il get this error:

Thanx,
Manu.
Did you specify a 'name' property in your form bean declaration in
struts-config.xml? 'Dyna' forms only have the properties you specify.
I've never used them, but I think the 'lazy' versions allow you to use
arbitrary properties without having to declare them.
