  Hi Michael,

the behavior you describe seems to be normal for JSF (in the moment I 
doesn't now that this has changed from JSF 1.1 to JSF 1.2).

When readonly is false the value will be submitted, but not written into 
the model. After an action with outcome "null" the same view root will 
be rendered again.
So the local value will be used instead of the actual value from the model.

If the action was completed and you do not need old value of other forms 
on that page, you should return an outcome different from "null" to 
create a new view.

Hope that helps.

Udo
