Updating cell data from async event

[initzero]

I've noticed that if I update my data array after the grid is rendered, the changes are not reflected in the grid.

I was able to find a way to fix this by adding a third argument to the $scope.$watch() call in ng-cells.js (line 1064).

                    scope.$watch(
                        'data',
                        function(newValue, oldValue) {
                            if (newValue !== oldValue ) {
                                scope.$$updateScrollPositions(oldValue);

                                // Update the data
                                scope.$$updateData();

                                // Refresh scrollbars
                                scope.$$refreshScrollbars();

                            }
                        }, true // add true here to watch value change
                    );

Hi @initzero,

Could you provide more information about how you update the data array for ng-cells? I'm assuming that you are modifying values in the array instead of providing a new array - which would indeed make the default $watch() miss this change.

                            // Update the data

                    }, true // add true here to watch value change
                );

Ah yes. I am modifying the array instead of replacing it with a new one. I see the distinction now. Thanks.

No worries. :-)
