>From the Sun javadoc for the renderer class: http://java.sun.com/javaee/javaserverfaces/1.1_01/docs/api/javax/faces/render/Renderer.html <quote> Individual Renderer instances will be instantiated as requested during the rendering process, and will remain in existence for the remainder of the lifetime of a web application. Because each instance may be invoked from more than one request processing thread simultaneously, they MUST be programmed in a thread-safe manner. </quote> So it seems that (1) is what is required by the spec.
