Cause an the argument resolver to be added to the resolver chain as specified in section 5.5.1 of the JavaServer Faces Specification.
It is not possible to remove an ELResolver registered with this method, once it has been registered.
It is illegal to register an ELResolver after the application has received any requests from the client. If an attempt is made to register a listener after that time, an IllegalStateException must be thrown. This restriction is in place to allow the JSP container to optimize for the common case where no additional ELResolvers are in the chain, aside from the standard ones. It is permissible to add ELResolvers before or after initialization to a CompositeELResolver that is already in the chain.
The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend {@link Application}.
