Re: [Springframework-developer] webflow: validator invocation strategy

I would say: just subclass FormAction and redefine either 
validate(RequestContext, Object, Errors) or invokeValidatorMethod(String, 
Object, Errors). Typically you could do that in a custom FormAction base 
class that you use for all form actions in your project.

Hi guys,

You recently extended validator invocation functionality in Web Flow
by calling a specific method on a validator instance. I propose to
make this behavior more generic. While I think calling a specific
method on the validator is a great way to do validation across
multiple pages there's a comparable strategy I would like to see
implemented.

I would like to call a collection of validators linked to a specific
string token in a map. The string token would be the equivalent of a
method name and would be defined in the flow config.

In order to implement this I propose to call specific validator
invocations through an interface that would allow different strategies
to be implemented.

Kind regards

Steven
