Not sure what you mean, Mike.
Every UIComponent has a setRendered(boolean) method that can be called
to specify whether that component is rendered or not. This method could
certainly be called from a PhaseListener.
Note that there is a slight flaw in the design of this method in my
opinion; the rendered property can be specified as either an EL
expression (ie stored as a ValueBinding) or can be a literal value set
via setRendered(). If a value-binding is used then setRendered() can
later be used to override that; however once rendered has been set using
setRendered, there is no way to go back to using an EL expression. In
other words, once you've decided to manually control the rendered state
you cannot go back to using the original EL rendered expression.
One way around this would be to use
// create a ValueBinding for the expression #{true}
setValueBinding("rendered", vb);
rather than
setRendered(true);
Cheers,
Simon

You can only set the rendered property of a component from the values
of a managed bean (unless you're using facelet functions or customized
el resolvers). Your managed bean can call whatever java code you
want it to.
If you give more specific details of what you're trying to accomplish,
maybe we can help you more.
