Xataface Forums

I'm working through the tutorial at
http://xataface.com/documentation/tutor ... ce_actions

When I copy and paste the code at the bottom of the page into
../FacultyOfWidgetry/actions/hello.php

then access the action by pointing the browser to
http://mysite/FacultyOfWidgetry/?-action=hello

I get the error:
Fatal error: Call to undefined method Dataface_Application::getRequest() in /srv/www/htdocs/FacultyOfWidgetry/actions/hello.php on line 7

Sorry there is a typo in the tutorial. I have fixed it now. The call to $app->getRequest() should be $app->getQuery()
