Working test for all cases (finally!):
<h5 if="${owner.isViewer}">Viewer is Owner</h5>
<h5 if="${!owner.isViewer && viewer.code!=401}">Viewer has App</
h5>
<h5 if="${!owner.isViewer && viewer.code==401}">Viewer does not
have App </h5>
Apurv and Vijaya: I have been following closely the development of OS
Templates, and I can tell that you changed the behavior of the
templates - now, when the user is not identified, you return a JSON
like this one:
{"message":"unauthorized: Get profile permission denied.","code":401}
Can we assume this won't change in the future, and the tests I posted
above will continue to work?
