Client-Side Validation Support
Reuse existing implementations
With the component initializer mechanism it's possible to join existing client-side validation mechanisms of existing component libs (if client-side validation is supported).
An available solution is the Trinidad Support of ExtVal. It joins the client-side validation mechanism of Trinidad based on annotations.
Furthermore, it's possible to implement a custom RendererInterceptor to build a custom client-side validation infrastructure.
(You will find a very simplified demo here: demo_102. Please don't use the demo as final solution. It just illustrates the required steps to get custom client-side validation up and running. So far there is no implementation you can use as final solution.)
Please notify us, if you would like to publish an implementation as ExtVal add-on.
