Subject Re: Validate method not working in Action after using Interceptor
Date Wed, 08 Jun 2011 06:34:20 GMT
In your interceptor, you're replacing the logic from the
DefaultWorkflowInterceptor with your own.  What you really want to do is
perform your work, then allow it to do it's job.  So, instead of return
invocation.invoke();, try  return super.intercept(invocation); and see if
that does more what you are looking for.
