No, it doesnt. But even if it did, it's not the problem. I already
have a working test for the "viewer has app" case: ${viewer !=null}
What I need is a working test for the negative case: "viewer does not
have app". I already made several tests, and none worked:
<h5 if="${viewer == null}">Viewer does not have App (A)</h5>
<h5 if="${!viewer}">Viewer does not have App (B)</h5>
<h5 if="${typeof(viewer) == 'undefined'}">Viewer does not have App
(C)</h5>
