_javascript_ Page added by Christophe Cordenier _javascript_ Why do i get "Tapestry is undefined" error on form submit? This client-side error is clear but can be awkward to solve, it means your browser has not been able to load tapestry.js file properly. The question is 'Why' ? It can be due to multiple reasons, some of them below: First, check if 'tapestry.js' is present in the head par of your resulting HTML page. If you have set the tapestry.combine-scripts configuration symbol to true, Tapestry generates one single URL to retrieve all the JS files. Sometimes, this can produce long URL that browsers are not able to retrieve. If you have included jQuery in conjunction with Tapestry prototype, that should generate conflict with prototype's '$' selector. In this case, i encourage you to put jQuery on top of the stack and turn on the jQuery.noConflict mode Also, if you have included a custom or third-party JS library on top of the stack that causes the _javascript_ parsing to fail, then check the _javascript_ syntax in those script If you have used a tool to minimize your _javascript_ libraries, this can lead to _javascript_ syntax errors, so check if it works with all the _javascript_ files unpacked.
