NullPointerException when using Terminal component

countercraft · 20 Feb 2010, 08:34

Hi, I tried to test the terminal component, but it gives me a NullPointerException. I've tested it with GlassFish v3/JSF 2/PrimeFaces 2 and Tomcat 6/JSF 1.2/PrimeFaces 1, but I had no success.
The page is very simple, just this:

Code: Select all

<?xml version='1.0' encoding='UTF-8' ?>
<!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:p="http://primefaces.prime.com.tr/ui">
    <h:body>
        <p:terminal />
    </h:body>
</html>

This is the stacktrace when I try to access the page:

Code: Select all

Does anyone know how to solve this?

Thanks in advance.

You have to wrap the terminal with h:form tag.
