angularjs ng-show with promise expression

Question

I\'m using ng-show with an expression that resolves to a promise that resolves to a boolean. When I do this I get the 10 digest iterations overflow.

This works as I think you intended it to. $q.when() returns a promise object, so ng-show is not getting a boolean value; it's getting a promise object.

Updated template:

  
    
non promise
    
promise
  

Updated Ctrl:

  $scope.returnsABoolean = ()->
    true

  promise = $q.when(false)
  promise.then((val) ->
    $scope.returnsAPromiseThatResolvesToABoolean = val)
