Add new components to component tree during PreRenderView event of postback

Is it possible to create new UIComponents and add it to component tree during the PreRenderView event of a postback? If so, how can I do it using public void onPreRenderEvent(@Observes PreRenderViewEvent e) in Seam 3?

Yes. I have been working with both the Mojarra team and the MyFaces team to establish the 'accepted' way of doing this. I have blogged their conclusions here:

The JSF EG are also looking at formalizing this in their spec:
