Hi,

I am using spring-modules 0.9. I am following chapter 17 on how to set up client validation with valang.

The server side validation is working.

But when I put <valang:validate commandName="userMessage" /> within <form:form commandName="userMessage"> ... </form:form>, it said: "org.apache.jasper.JasperException: java.lang.IllegalArgumentException: No valang rules for command 'userMessage' were found in the page context."

Does anyone know about this problem? What can I do to make valang know that userMessage has rules?

Thanks,

Derek
