javascript - AngularJS/ng-grid - Updating array with splice doesn't updates UI

Question

I am trying to update ng-grid with array splice. I have a plunk here.

Add button adds new row. Update button updates last item in the array.

1. Select a row & press update button. Nothing happens.
2. Press add button. Now UI gets updated with new element & as well as the previously updated element.
3. Same behavior gets repeated again & again.

I tried $scope.$apply. I get:

“Error: $apply already in progress”

I even tried by placing $scope.$apply block inside a setTimeout call. Again the same error!

Any pointers!

Thanks!

That's because data $watcher in ng-grid (incorrectly) compares the data object for reference, instead on object equality. You might remedy this by setting the third parameter to true in data $watch function (line 3128):

$scope.$parent.$watch(options.data, dataWatcher, true);
