RPCAdapter and JSF   

Suppose JSF and Ajax are used in the same project. JSF Managed Bean needs to be updated via AJAX call. Is there a way to get Faces Context from inside the object invoked by RPCAdapter?

Another way around:
Is there a way to get both request and response objects from RPCadapter (I know request is actually available) and instantiate Faces context using Faces factory given these two objects available?

Thanks!
