In my widget I would like to change the messaging if the visitor does not have the widget installed. But I don't see a way to perform this check correctly
<Require feature="opensocial-0.9" /> <script xmlns:os="http://ns.opensocial.org/2008/markup"; type="text/ os-data"> <os:ViewerRequest key="theviewer"/> </script> <script type="text/os-template"> <div if="${'theviewer' != ''}"> <p>1.Viewer is not null</p> </div> <div if="${empty theviewer }"> <p>2.Viewer is empty</p> </div> <div if="${ 'theviewer' =='' }"> <p>3.Viewer is empty</p> </div> </script> 1.Viewer is not null, is printed always 2.Viewer is empty , is never printed. 3.Viewer is empty, is never printed. What is the correct syntax? Is this documented somewhere in entirety?
