The problem described must be commonplace and surely must have been discussed before. Apologies for bringing it up again.
I have a simple action class named say Hello in struts.xml, and have the validations specified in xml (Hello-validation.xml). The messages come up when invoking Hello. How do we prevent the messages from appearing when invoking 'hello.action'? They should appear only when the user posts the form.
Read somewhere that S2 will ensure this when the action class returns INPUT. That does not seem to work. A bit curious about the best practice to follow here...
