        }

json.js

"controlOwners": [{
    "workerKey": -1093,
    "sourceFeed": null,
    "statusLookUpCode": null,
    "externalId": null,
    "createdUserText": null,
    "createdTimestamp": null,
    "modifiedUserText": null,
    "modifiedTimestamp": null,
    "stdId": "ZK84T1N",
    "ccId": null,
    "empClasId": null,
    "deptId": null,
    "fullName": "Rajasekaran, Shanmuga",
}],

Answer 1

My guess is as I stated in my comment above, that you have the incorrect casing in your reference to controlOwners. You have spelled it with a lower case 'o' ('controlowners'), when it should be upper case ('controlOwners'). And hence you are getting an undefined error.

Answer 2

first make sure that this isn't a typo. You have both:

controlOwners
       ^

and

controlowners
       ^

in the JSON and code.

Then if the typo is just in your question and not in your code, and depending on how you're using $scope.selectedOwners elsewhere, you might not want to replace the reference of the list in the if statement, but rather have it update the existing list (even if you have to clear it first).

But obviously, if your code has exactly :

$scope.selectedOwners = [];
if ($state.is('app.editControl')) {

and not the if in a callback that might be triggered at another time, then ignore that.
