[html-formfu] some questions

I'm new to HTML::FormFu (never used HTML::Widget) either, and have a 
couple of questions:

The first one is how to easily utilize values which have been altered by 
FormFu's validation.  An example would be the TrimEdges filter.  If a 
user enters a value like "  foo  " and we need to redisplay the form, I 
would like the prefilled value to be "foo".

Secondly, if I want to add a complex validation routine, like checking 
to see if a US address is USPS deliverable, is this best done as a 
callback constraint, or a validator?  If validator, can someone point me 
to an example of a validator?  The only useful information on validators 
seemed to be t/validator.t
