P:commandButton com erro estranho

Front-end
#1

Olá pessoal estou tendo problema em usar o componente do primefaces-2.2.1

retorna um erro no console, meu exemplo esta assim:


<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:p="http://primefaces.prime.com.tr/ui">

<h:head>
	<title>Estágio Supervisionado</title>
	<h:outputStylesheet library="css" name="estilo.css" />
</h:head>

<h:body>

		<h:form>
			<p:commandButton value="Registre-se"  action="/publico/usuario.jsf" />
			<h:commandButton action="#{usuarioBean.novo}" value="Registre-se" />
			<h:commandLink action="#{usuarioBean.novo}" value="Registre-se">
			</h:commandLink>
			
		</h:form>

</h:body>
</html>

somente no componente do prime que acontece o erro:

alguem tem idéia do q seja? Podem me ajudar

#2

qual esse componente:id j_idt3? será q é msm o p:commandButton? pra resolver só colocar o nome no id dele…pq o erro lá fala de estouro de um array, ou seja, acessando uma posição do array q não existe, tipo vc tem 3 registros salvos no array, mas tenta acessar o último digitando acesso[3] mas o array começa no zero, ou seja, seria tipo acesso[2] pra acessar o último saka?

#3

Sempre usei o action acessando algo do Bean. Veja se não é esse o problema. Tente:

<p:commandButton action="#{usuarioBean.novo}" value="Registre-se" />

E direciona lá pelo método “novo” mesmo.
