Re: [Springframework-developer] Design question on AbstractWizardFormController

[Michael Y. <sp...@on...>]

I've also seen quite many methods being final in Spring,
which I think is unnecessarily restrictive.  One can never
anticipate how things will be used by end users.  The
disadvantages far out-weigh the advantages.

So, please, don't tie users hands too eagerly.

Thanks!  /Michael.
