I recently encountered an issue with an infinite loop involving angularjs $q and promises. Here's the code in question:
<a ng-hide="!isTechnician()" class="pull-right" href="#/admin/techniciansState"><span
class="glyphicon glyphicon-map-marker"></span> Estado del técnico
</a>
Upon further examination, I discovered this javascript code snippet:
$scope.isTechnician = function () {
if (!$scope.notCheckTechnician) {
SecurityService.getCurrentUser().then(function (user) {
if ($.inArray('technician', user.roles)) {
return true;
} else {
return false;
}
});
}
};
var SecurityService = function($resource, $q, $rootScope, API_URL) {
// REST service definition
var Security = $resource(API_URL + '/security/:action', {
action: "@action"
}, {
'currentUser': {
method: 'GET',
isArray: true,
params: {
action: 'current-user'
}
}};
var getCurrentUser = function() {
var deferred = $q.defer();
var user = Security.currentUser(function() {
if (user.length > 0) {
_setCurrentUser(user[0]);
deferred.resolve(user[0]);
} else {
_setCurrentUser(null);
deferred.reject('Not authenticated');
}
}, function() {
_setCurrentUser(null);
deferred.reject('Not authenticated');
});
return deferred.promise;
};
But then came the error message:
Error: [$rootScope:infdig] 10 $digest() iterations reached. Aborting!
Watchers fired in the last 5 iterations: []

Curiously, I couldn't find any watchers in my controller. What could be causing this?
