Primefaces extensions ajaxErrorHandler not working

jsf-2 primefaces wildfly-8 primefaces-extensions

On WildFly 8-1 I have primefaces-5.1.jar and primefaces-extensions-2.1.0.jar in my webapps WEB-INF/lib directory.

I have configured WEB-INF/faces-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config
  xmlns="http://xmlns.jcp.org/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
version="2.2">
  <application>
    <el-resolver>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerELResolver</el-resolver>
  </application>

  <factory>
    <exception-handler-factory>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerFactory</exception-handler-factory>
  </factory>
</faces-config>

I have the following JSF.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
  xmlns:h="http://xmlns.jcp.org/jsf/html"

<h:body>
  <h:form id="form">
    <pe:ajaxErrorHandler body="ERROR"/>
    <p:commandButton actionListener="#{dossierResumen.excepcion}" value="Excepción"/>
  </h:form>
</h:body>
</html>

where DossierResumen#excepcion() is

public void excepcion() {
  throw new NullPointerException("EXCEPCION! EXCEPCION!");
}

When I click the button, I get no popups at all; the page gets redirected to the URL for error 500 defined in web.xml. In the logs, I get the following wall of stacktrace:

What am I doing wrong?

There are two modes in that component: simple and extended mode.

In the simple mode, you don't need to specify anything in your faces-config.xml. So you can delete these lines:

<application>
    <el-resolver>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerELResolver</el-resolver>
</application>

<factory>
    <exception-handler-factory>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerFactory</exception-handler-factory>
</factory>

Or delete the whole faces-config.xml file since it's the only thing you have in there. Then you can test simple mode, which is working fine without defining anything else in your web.xml. This might be enough for your needs.

From the error trace, it seems that in extended mode (with that faces-config.xml configuration), the component needs to have an error page defined in your web.xml. You don't want a redirection to an error page, so if you add the following code to your web.xml for example works, but not for your needs:

<error-page>
   <exception-type>java.lang.Throwable</exception-type>
   <location>/error/500.xhtml</location>
</error-page>

Anyway, it's HIGHLY recommended to use the p:ajaxExceptionHandler native component since it looks like the authors of PrimeFaces Extensions will probably remove the component in the future since it's no longer necessary (link) already removed the component in version 3.2.0. (link)
