                Session.set('message', error.error + ': ' + error.reason);

});

MyApp = {}
MyApp.navigate = function(route) {
    Router.navigate(route, {trigger: true});
    // OF COURSE, this won't work because it will flush the message immediately after the redirection (Because of the automatic update in the templates)
    // So I would need to set it only on the next MyApp.navigate() call
    Session.set('message', undefined);
