[Springframework-developer] Design question on AbstractWizardFormController

[Steve G. <sg...@ya...>]

I posted this in the user group but I think its more
relevant for the developer group. My colleague is
having a problem with the
AbstractWizardFormController. He posted the message to
to the forum only, so I figured I'd also post it here:

---------------------------------------------
IMHO, WizardFormController has some limitations with
the way it handles pages. For example, In a 5 step
process, user steps into page 4, and then hit back
button on his browser, to page 2 and resubmit form.
the backing-form is still in session, so it will try
to bind and validate. It get current page which will
be 4. validation specific to page 2 was not called but
validation of page 4 was invoked. 
I would like to rewrite WizardFormController to
overload getCurrentPage() method, but it was declared
final. Neither could I use an interceptor to setup the
pages because getPageSessionAttributeName() is
specific to the class name. Currently, I have to
change currentPage variable inside onBindandValidate()
method to use some param passed in from request. Or I
could rewrite AbstractWizardFormController to remove
those final methods. 

Any suggestions?

Best Regards,
