Hi cocooners
I'm trying to add a new application in the portal engine's
authentication handler. The goal is to activate a pipeline at login and
logout and put data in a separate session context. Here is the sniplet
of the sitemap
...
            <authentication-manager>
                <handlers>
                    <handler name="portalhandler">
                       <redirect-to uri="cocoon:/login" />
                       <authentication
uri="cocoon:raw:/sunrise-authuser"/>
                       <applications>
                            <application loadondemand="true"
name="portal">
                                <configuration name="portal">
                                    <profiles>
							...
                                    </profiles>
                                </configuration>
                            </application>
                            <application name="MyApp">
                            	<load uri="cocoon:raw:/load-MyData"/>
                            	<save uri="cocoon:raw:/save-MyData"/>
                            </application>
                       </applications>
                    </handler>
                </handlers>
            </authentication-manager>
...
            <map:match pattern="load-MyData">
                <map:generate src="profiles/MyData.xml" />
                <map:serialize type="xml" />
            </map:match>
            <map:match pattern="save-MyData">
                <map:generate src="resources/save-MyData.xml" />
                <map:transform type="session" />
                <map:transform type="write-source" />
                <map:serialize type="xml" />
            </map:match>
...
If I understand the documentation of the authentication framework
http://localhost:8888/docs/developing/webapps/authentication.html
the uri load-MyData is trigger at login and I hope save-MyData trigger
at logout. When I do a login I got this NPE.

Obviously I miss something, but what?
