1. Shuo Liang 2014-06-18 seems a small bug here. For now, you'd better use view as the parent level, and I will notice to our engineer team to take care of this bug.
2. Shuo Liang 2014-06-18 I can reproduce this problem with: Ti 3.3.0.RC, iOS Simulator 7.1
3. Eric Merriman 2014-06-18 [~fcasali] Could you take a look and see if you can narrow down root cause? I asked if you could determine if regression, but Sam mentions he can see it with 3.3.0, so that combined with the reported affected version of 3.2.3 (assuming alloy 1.3.1 here) makes me think not a regression in the SDK nor Alloy, but not sure before 3.2.3 or 1.3.1.

5. Tim Poulsen 2014-06-27 PR: https://github.com/appcelerator/alloy/pull/464 Test app: https://github.com/skypanther/alloy/tree/ALOY-1055/test/apps/testing/ALOY-1055 Plus, also test using the ui/listview test app Both should run without error and display the listviews. The 1055 test app should display the listview (which has templates) within the scrollable view, swipe right for the second view, which also contains a listview (without a template).
6. Matej 2014-06-28 I have got one question. If I do something like this:

      <Alloy>
          <Window>
              <Widget src="xxx">
                  <ListView>
                      <Templates>
                          <ItemTemplate name="first">
                             <!-- ... ... ... -->
                          </ItemTemplate>
      
                           <ItemTemplate name="second">
                             <!-- ... ... ... -->
                          </ItemTemplate>
                      </Templates>
                  </ListView>
             </Widget>
          </Window>
      </Alloy>
      

   And then in the widget I'll check arguments[0].children it contains ItemTemplates and as the last thing is the ListView. Is it normal? It shouldn't work like this or am I wrong?
7. Tim Poulsen 2014-06-30 [~sko] That appears to be an unrelated issue with the ListView parser. I've added ALOY-1064 to describe and track the issue you noted. On that ticket, I noted a workaround: reference the children array like this:

      var kids = _.compact(arguments[0].children);
      Ti.API.info(JSON.stringify(kids));
      

8. Matej 2014-06-30 Tim Poulsen, yes I know sorry for that I just wanted to know if that's really an issue or normal behaviour.
