Fundamental question on tabs

ionic-v1
1

hi,
How do i solve the following problem : (using the basic tutorial example with friends).

if I have 1 tab that reads the list such as :
.controller(‘ChatsCtrl’, function($scope, Friends, $http) {
$scope.friendsCounter = Friends.all().length;
})

then in another tab user adds a friend. However switching back to this tab, still the old count is displayed because the scope.friendsCounter was only populated initially and I am not sure how to reset it.

Any ideas?

Is Friends configured as service?

Check out ion view caching introduced in beta 14, your view is cached. You need to update it.

yes. that’s exactly what’s going on. so how do i update my view?
is that through $scope.$apply?

you need to catch ionview.enter event and reload your data from the server

i am going to disable caching for now. Performance is not an issue for me at this point.
