But the prerender() is called before the tag being processed. when the prerender() is called, the reference is still null if this is an initial request. Tree hasn't been constructed, when the prerender() is called. I guess maybe if I want to set a initial value of a component when the page is viewed the first time, the reference to the component must be assigned using a *new* keyword.
Not quite. IF you use a "binding" attribute on your component, AND IF the getter method on your backing bean returns a component instance that has been previously configured (in the backing bean's prerender() method), THEN the component tree will include *your* instance instead of creating a new one. The nitty gritty details of how this works are found in Section 3.1.5 of the JSF 1.1specification. Craig
