Yes. As I don't think there is any other option available. And I wanted to validate my understanding regarding that in this thread.
Here is the problem situation - 1. I cannot execute the normal JSF lifecycle.execute() as for that the ActionRequest needs to have MyFacesGenericPortlet.VIEW_ID populated as one of the request parameters with the target view jsp/xhtml. 2. So I need to directly go to doView(). At this point the request and response in facesConfig is changed to RenderRequest and RenderResponse. The RenderRequest doesn't content the original request parameters which were in the ActionRequest, unless those parameters are explicitly populated using request.setRenderParameters(). 3. The renderView() will in turn call the facesRender() and which will in turn call the nonFacesRequest() (as the VIEW_ID is null) 4. The nonFacesRequest() method will first set the default view as the view and will eventually call the lifecycle.render() 5. The lifecycle.render() will initiate the bean referred in the default view page but it cannot populate the bean attributes with the original request parameters as those parameters are not available in RenderRequest (unless explicitly populated as methioned in step 2). So as a solution I thought - 1. In processAction() we can populate all request parameters of ActionRequest in RenderRequest using request.setRenderParameters(). 2. In the constructor of the bean (which is called in step 5 mentioned above) access them from RenderRequest and populate the bean attributes. I've also thought of another approach where I can create the target bean in processAction() using the request parameters in ActionRequest and keep the bean in session. However, this solution will not be generic as one can not access the target bean names in generic way at processAction() method. Any other viewpoint/suggestion in this regard would be highly appreciated.

Ahh, I see. So you're trying to reference the action parameters from the Render?
