Hi Michael,
for actions used in partial rendering you should always return null!
I the action returns a string than a full reload is made!
I suggest using actionListener for partial actions.
When rendering partially only the requested subview (plus the action
component if outside) is processed on the server.
In your example you request reload of box2, which means the content of
box2 is processed and stored in the model.
In the action string2 is set to string1 but string1 was not processed
so it is still null here.
Have you in helmuts example really changed the value of
renderedPartially to the suggested panel arround both boxes?
Regards,
Volker
