I use tapestry-beanvalidation and tapestry-jquery. As a result, when I open up a page, I get a javascript error in tapestry-beanvalidator.js:15:
Cannot set property 'notnull' of undefined The offending line is : Tapestry.Validator.notnull = function(field, message, spec) Uncaught TypeError: Cannot set property 'notnull' of undefined { Tapestry.Validator.required(field, message); }; This is obviously the client-side validation for beanvalidation, possibly depending on Prototype. I was going to look to see if I can exclude the JS from loading, but I was wondering if anyone else has run into the same issue and if there is a better way of dealing with it. Cheers, Alex K
