in your sample you need a
@Persist("flash")
private Contact contact ;
in your view contact
But using activate passivate would be smarter.
To complete Stephan advice
I suggest to read also activate passivate sample
http://jumpstart.doublenegative.com.au:8080/jumpstart/examples/navigation/onactivateandonpassivate/3
You will need to replace your actionlink by an pagelink with the same
t:context="contact.id
and add the following code to the your view contact
private Long _Id;
// The code
// onPassivate() is called by Tapestry to get the activation context
to put in the URL.
Long onPassivate() {
return _Id;
}
// onActivate() is called by Tapestry to pass in the activation
context from the URL.
void onActivate(Long Id) {
_Id = Id;
}
// setupRender() is called by tapestry at the start of rendering -
it's good for things that are display only.
void setupRender() throws Exception {
// Convert the id into a Person.
contact = dao.getById(_Id, Contact.class);
}
