[opencms-dev] NullPointerException with template on xml custom content

[Thierry Collogne]

Hi all,

I have created a custom xml content. I declared an artice.jsp template for 
each xml content item.
But now I want to declare a template on top of the article.jsp template.

Before adding the the template on top of to artice.jsp everyting was working 
fine, now I always get a nullpointer.

This is the schematic view of the current situation

news_0001.html
news_0002.html
                        -> article.jsp template
                            -> general.jsp template

This is the code from the article.jsp


<%@ page session="false" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>

<cms:include property="template" element="head"/>


	<cms:editable/>

	<div class="element">
		<cms:contentload collector="singleFile" param="${opencms.uri}" 
editable="true">
			<h2><cms:contentshow element="Title" /></h2>
			<cms:contentcheck ifexists="Image">
	 			<img src="<cms:link><cms:contentshow element="Image"/></cms:link>">
			</cms:contentcheck>
			<p><cms:contentshow element="Text"/></p>
		</cms:contentload>
	</div>

<cms:include property="template" element="foot"/>




I think it has something to do with the inclusion of the head element.

This is the stacktrace

Does anyone know what could be causing this? Is it maybe not possible to add 
a template on top of another template?
