Populate <select> options from a webservice in a custom stencil

I'm on developing a custom stencil in Activiti 1.7 where I want to populate values from a Webservice in a dropdown box. So far, with my current approach, it works fine with the exception that I'm not able to manage the current selection anymore after the "Save" button in the task was clicked. Maybe my approach is not the right one? Can someone give me advice in best-practice, please?


Here is my current runtime template, I want to achieve this with ng-options parameter at the <select> level instead of ng-repeat:

<div ng-if="field.type !=='readonly'" ng-controller="myCompanyCodeController">
<select class="form-control" id="myCompanyCodeSelect" name="myCompanyCodeSelect" ng-change="updatedata()" ng-options="company.value for company in companycodes track by" ng-model="myCompanyCode" >


And this is the main part of the controller:

angular.module('activitiApp').controller('myCompanyCodeController', ['$rootScope', '$scope', '$http',
    function($rootScope, $scope, $http){
         $http.get('http://localhost:8080/activiti-app/app/rest/getMyCompanyCodes').success(function (data) {
         var options = [];
         for(var i = 0; i < data.length; i++) {
             var obj = data[i];
                          id :,
                          value : obj.label
         $scope.companycodes = options;
         return options;

The behavior is, that if a user clicks on the "Save" button of the task, the page will be reloaded. Therefore the controller is executed again, and therefore even the Webservice is called again. The issue is now, that I don't know how to pre-select the current selected value of the dropdown again, once the page was refreshed? Always the first option appears. I can see, that in parameter $scope.field.value the selected value remains and is still there after the refresh, but the ng-model is gone. On the other hand, I really don't need to call the Webservice each time a user clicks on "Save" to fill the ng-model again. Should I try to handle this different as well?


Thanks for any advice!
