Oh,yeah,I see, that's why you use new keyword in the code above.
private HtmlOutputText dynamicText = new HtmlOutputText();
Then,I have a pretty weird idea. If you dosen't new a HtmlOutputText,will
there be a NullpointerException popped up in this case?

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

Graig, that's very kind of you.
Are these aproachs feasible,when the page is requested by an inital request?
When an inital request arrives, the view restoring phase is skipped and JSF
goes to the response rendering phase directly. Then there should be no
component tree constructed at all ,when

You are correct. There is special handling defined in the Restore View
phase. If that phase discovers that there is no state to be restored
, then JSF will immediately forward to Render Response phase.
So, how do you make sure that the right

So, how do you make sure that the right dynamic data gets
loaded so that the

handy. If your
backing bean implements the ViewController interface, then
prerender() will
get called just before the JSP page is invoked. This is

You can indeed register a listener with a phase-listener declaration --
you get an application wide singleton that has the same lifetime as your
application. However, it's also possible to add a phase listener

In JSF, when a request arrives, it should go through 6 phases to process the
request. The first stage is called Restore the View , and the last stage is
called Render the Response. I wonder where JSP works in these 6 phases. If
JSP only works in the last phase, how can JSF restore the view first
