$.destroy undefined exception on Collection callback


    • Type: Bug
    • Status: Resolved
    • Resolution: Invalid
    • Affects Version/s: None
    • Component/s: Alloy
    • Labels:
    • Environment:

      AppC CLI 7.0.10
      TiSDK 7.5.1.GA, Alloy 1.13.9
      MacOS 10.14.2


      I have two instanced Collections in one of my Views with data binding. I have the close of the view hooked up to a cleanup function which calls '$.destroy'. Whenever that destroy function is thrown I get an undefined exception Uncaught ReferenceError: __alloyId488 is not defined. In the alloy code, I see that id is the callback to my collection, but I'm unsure of what could be happening to it. I'm only doing a reset on the collection once I get data back from a request.

          var __alloyId487 = Alloy.Collections['$.Experts'] || $.Experts;
      function __alloyId488(e) {
          if (e && e.fromAdapter) {
          var opts = __alloyId488.opts || {};
          var models = __alloyId487.models;
          var len = models.length;
          var __alloyId483 = [];
          for (var i = 0; i < len; i++) {
              var __alloyId484 = models[i];
              __alloyId484.__transform = TF.transformExpert(__alloyId484);
              var __alloyId486 = {
                  properties: {
                      backgroundColor: "transparent",
                      selectedBackgroundColor: Alloy.CFG.design.colors.primary,
                      itemId: __alloyId484.__transform.expertusername
                  expHeader: {
                      text: 'Preferred ' + __alloyId484.__transform.field + ' Expert'
                  expImg: {
                      image: __alloyId484.__transform.prefImage
                  expName: {
                      text: __alloyId484.__transform.expertname
                  expCompany: {
                      text: __alloyId484.__transform.company
                  expPhone: {
                      text: __alloyId484.__transform.expert_ph1
                  expEmail: {
                      text: __alloyId484.__transform.expert_email
                  expWeb: {
                      text: __alloyId484.__transform.webAddress
                  template: "expertCard"
          opts.animation ? $.__views.expSection.setItems(__alloyId483, opts.animation) : $.__views.expSection.setItems(__alloyId483);
      __alloyId487.on('fetch destroy change add remove reset', __alloyId488);
      $.__views.propSection = Ti.UI.createListSection({
          backgroundColor: "transparent",
          id: "propSection"

      Both collections are included in the XML as follows

          <Collection id="Properties" instance="true" src="Property" />
          <Collection id="Experts" instance="true" src="Expert" />

      I have tried multiple different 7.X sdk versions, as well as different appc CLI versions to see if it was an error with their specific bundled alloy version, but still received the error. Same even after checking out a previous commit of the project where I know the error didn't exist but just keeps cropping up.

      Completely reinstalled the cli and all my SDKs, but still getting the error. Hopefully commenting out the destroy and manually calling .off() on both Collections is enough of a workaround for now.
