Howdy all,
I'm creating a custom JSF component that relies on some javascripts and I'm using
the weblets library to retrieve them. When weblets generates the URL for resource it ends
up being something along the lines of: /myapp/weblets/resources/container.js.seam. Since
it has a .seam extension, it's attempting to load the page context and generating a
null pointer exception because there is no view root for javascript file.
My question, is there a configuration in the face-config.xml or web.xml to prevent it from
attempting to load the context? Below is my configuration and the exception that I'm
receiving. Thanks.
