You forget the redirect after post, or even when nothing is submitted.
First render of the page.... refresh...
I have been reading about the redirect after post pattern (of which I wasn't
aware) here
http://www.theserverside.com/tt/articles/article.tss?l=RedirectAfterPost and
now I understand your point.
Will wicket always work in this mode? Is this configurable?
Another thing that I asked before in this thread and of which I'm still not
sure is about page creation. When will pages be created? Every time they are
accessed or just the first and then serialized into the session? This is
relevant to form model management because if my model discriminates between
the first time the form is entered and other times (for example after
resubmission), things won't work as expected if the model is instantiated
just once along the entire session (instead of once every time I enter the
form page for a new, say UserProfile, update).
Cheers,
Carlos
