My next app will have a rich client side (currently I am thinking ExtJS) with a JAX-RS back-end. (JSF/facelets can give me neither the performance nor the flexibility that I aim for.) OTOH I'd like to generate the pages with pre-filled data (to avoid costly, unnecessary round trips to the server) and with page-static content dynamically generated on the server. I can use Seam components and bijection in the backend (with Seam's RESTEasy integration). However I am dearly missing the ability to use seam defined components in my EL.
Is there a way to make that work? JSP knows about custom EL resolvers, too, right?
