Description

tapestry-beanvalidator is using MarkupRendererFilter to include the tapestry-beanvalidator.js in every page. Which means that if you have the tapestry-beanvalidator dependency in your project you end up importing many tapestry javascript files that you may not need. Even for an empty page, if you have tapestry-beanvalidator as a dependency it will include a dozen javascript files.

A better approach would be to have a JavaScriptStack for tapestry-beanvalidator.js and then use a worker to import the stack ONLY when there is a form present. The tapestry-jquery project has a nice example of this, FormResourcesInclusionWorker
