Description

When you have used a SearchBar to filter out all items in a ListView that then resizes because it is contained in a Popover that resizes because the soft keyboard hides, the app crashes. *NOTE:* This issue looks very similar to TIMOB-18260, but the fix for that bug doesn't fix this bug and the stack trace is very different as well. Looking at this stack trace the issue seems to be related with resizing the list and containing it in a Popover is just a typical situation where this happens. The actual exception is:

*** Terminating app due to uncaught exception 'NSRangeException', reason '*** -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array'

Test Case

Run an app with the following code on an iPad. Best is to use a device with no hardware keyboard. In Simulator you need to use Cmd+K at first to bring up the soft keyboard. 1. Tap the button to open the popover. 2. Tap the searchbar to bring up the soft keyboard, resizing the popover and list view. 3. Search for anything to filter out all items (since they don't have a searchableText. 4. Hit *Search* or the dedicated key to hide the soft keyboard. 5. See the app crash soon after.

var w = Ti.UI.createWindow({
  backgroundColor: 'white'
});

var b = Ti.UI.createButton({
  title: 'Click Me'
});

b.addEventListener('click', function() {

  var cw = Ti.UI.createWindow({
    width: 300
  });

  var items = [];

  for (var i = 1; i <= 50; i++) {
    items.push({
      properties: {
        title: 'Row #' + i
      }
    });
  }

  var lv = Ti.UI.createListView({
    searchView: Ti.UI.createSearchBar(),
    sections: [Ti.UI.createListSection({
      items: items
    })]
  });

  cw.add(lv);

  var p = Ti.UI.iPad.createPopover({
    contentView: cw
  });

  p.show({
    view: b
  });
});

w.add(b);
w.open();
