add the code for a widget (widget.xhtml) once but use it twice in same webpage, possible ? How?

I have a widget in my application that I need to display at two places(once in main p开发者_如何学编程age body and once through dialog box). Currently its code has been added twice in the page. Now I was thinking, If there was a way I could just include it only once and show the same instance in the dialog box, as in the main page body.

Can you suggest a way for this?

I'm Using:-

JSF 2.0 with Facelets

Primefaces 3.0 M3 Snapshot

JSF 2 has exactly the feature you want: it's called composite components. I bascially allows you to write a bunch of Facelet code into a file and use it just like any other JSF component, pass parameters to it, etc.
