Within my directive controller, I've implemented a $watch function as follows:
$scope.$watch(function () {
return service.abc;
}, function(newVal, oldVal) {
$scope.abc = {abc: newVal};
});
However, I've encountered issues with the variable becoming undefined when utilized in other controllers. To address this problem, I created another watch:
$scope.$watch('abc', function () {
console.log($scope.abc);
});
Observing this second watch, I noticed that the abc object is initially defined with the value from the service, but then it becomes undefined afterward. Despite taking precautions by using:
$scope.abc = {abc: angular.copy(newVal)};
To prevent any modifications to the object, it still ends up being undefined. Even after experimenting with different variable names and utilizing the vm controllerAs syntax, the issue persists. What could be causing this unexpected behavior? It's crucial for me to pass this object into a directive, make changes in the parent controller, and have those modifications reflected in the inner directive controller.
