Description

Our partner Alfresco discovered this issue when trying to build their Alfresco SDK test harness for Android, using SDK 3.1.3. This is stopping them progressing with the Android version. The issue is in the ListViews in the AlfrescoTestHarness Alloy project. These work fine for iOS, but cause an exception on Android. I have attached the source zip to this ticket, and this is the exception that occurs, during app start up (before any of our code is called):

I couldn't reproduce the crash running AlfrescoTestHarness. I do see a login screen with credentials pop up. Here's another test case that will produce the same crash on start up:

   var sections = [];
   var animalsSection = Ti.UI.createListSection({ headerTitle: 'Animals'});
   	var animalsDataSet = [
   	    {properties: { title: 'Deer', searchableText:'Animals Deer', itemId:'3 0'}},
   	    {properties: { title: 'Dog', searchableText:'Animals Dog', itemId:'3 1'}},
   	    {properties: { title: 'Cat', searchableText:'Animals Cat', itemId:'3 2'}},
   	    {properties: { title: 'Elephant', searchableText:'Animals Elephant', itemId:'3 3'}},
   	];
   	animalsSection.getItems();
   	animalsSection.setItems(animalsDataSet);
   	sections.push(animalsSection);
   	var listView = Ti.UI.createListView({top: 250});
   	listView.sections = sections;
   	
   	var win = Ti.UI.createWindow();
   	win.add(listView);
   	win.open();
