I am using Eclipse to work with PrimeFaces like this:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.prime.com.tr/ui"
template="/template/ui.xhtml">
I saw Bozho question and answer.
So it works for me only for h and f tags and not for p (primefaces) tag! How can it autocomplete primefaces tag?
