Description

When trying to set a list, via "Ti.App.Properties.setList", with an object that has a null value property, I get an Application Error: "Attempt to insert non-property list"

var names = [{
    name: "One"
}, {
    name: null
}];
Ti.App.Properties.setList("names", names);

This error does not happen on Android 6.0.1. *Note:* This issue seems similar to [TIMOB-13127]

This should be in TIMOB and not TC.

I guess this won't get fixed because nobody else has bothered to report it?

I can report it again. Still in SDK 5.4.0

PR (Core-SDK): https://github.com/appcelerator/titanium_mobile/pull/8371 PR (Unit-Test): https://github.com/appcelerator/titanium-mobile-mocha-suite/pull/4 Using a generatic attempt too loop through dictionary-values in setList to convert between null- and NSData-values that are required by the internal iOS-API. The test-case contains all kind of possible values, from dictionary (object) over null, undefined, string, number and boolean. Demo:

   var win = Ti.UI.createWindow({
       backgroundColor: "#fff"
   });
   
   var btn1 = Ti.UI.createButton({
       title: "Set list",
       top: 30
   });
   
   btn1.addEventListener("click", function() {
       var names = [{
           name: "One"
       }, {
           name: 1
       }, {
           name: ""
       },
       null, {
           name: true
       }, 1, "", null, false];
       Ti.App.Properties.setList("names", names);
   });
   
   var btn2 = Ti.UI.createButton({
       title: "Get list",
       top: 60
   });
   
   btn2.addEventListener("click", function() {
      Ti.API.warn(Ti.App.Properties.getList("names", []));
   });
   
   win.add(btn1);
   win.add(btn2);
   win.open();

Expected result: - No crashes in getting and setting the property-list - null- and undefined-values are properly accepted in both setter and getter
