you can certainly go ahead and try your suggestion.
It will work and it would be a nice, OO and reusable solution.
Another solution would be to :
1) Add a message property in the .page
2) Conditionally include the message in the .html
3) Update / Set the message string in the listener method that gets invoked on submit.
But I would really go on with the solution you proposed.
Keep in mind that you can always pass as many additional parameters as you want to your validation bean.
Take a look at http://jakarta.apache.org/tapestry/doc/DevelopersGuide/spec.bean.html
and at

Bear with my stupid questions...I'm currently using StringValidator to validate user input and display error messages. Beyond that, what I need to do is to validate the user input against a database ( for user account creation ). So, for example if the username already exists I want to display this on the page. Is this the correct way to go about things (i.e. extend BaseValidator?)
Much appreciate your patience..
Yiannis.
