With BeanEditForm Person need not be instanciated in onActivate. That is
done "automagically" by the component itself.
The Exception surely refers to the id. Id being the only number in your
Person class. Although I do not know, why that would be a problem for
Tapestry, you surely would not want the user to edit the database id. So
try the following. You might get rid of your problem with that:
public class Persion {
...
@NonVisual //<-- that excludes this member from the generated
// BeanModel. This could also be done manually whit "exclude".
// (see BeanModel for further information.
public Person getPerson() {
return person;
}
...
}
