> If a validation error happens (validation interceptor), the workflow interceptor redirects the user to the statically configured 'inputResultName'.
> This is fine most of the time.
> However, when using the conversation scope interceptor (WW-1514), for instance, the 'inputResultName' cannot be determined statically. Let's say you have an action, with
> @SomeValidations
> submit1()
> @SomeOtherValidations
> submit2()
> @AnotherSetOfValidations
> submit3()
> If you're currently submitting the step 2, and @SomeOtherValidations report an error, you certainly do not want to go back to step 1.
> So, the attached files are a modified  DefaultWorkflowInterceptor that will ask the action to determine the input name if it implements a given interface;
