I'm using Primefaces 4.0 + JSF 2.1 + Bootstrap 3 and when I try put "h:form" in block bellow I got a error:
Caused by: java.lang.IllegalStateException: Cannot create a session after the response has been committed
So, this code bellow throws the error above:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<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:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui">
<h:head />
<h:body>
    <ui:composition template="/templates/template.xhtml">
        <ui:define name="content">
            <h:form>
             hello world
            </h:form>
        </ui:define>
    </ui:composition>
</h:body>
</html>
If I remove the "h:form" the 'hello world' is rendered.
I tried this is my web.xml, but didn't work too:
<context-param>   
<param-name>
    com.sun.faces.writeStateAtFormEnd</param-name>   
<param-value>false</param-value>   
</context-param>
