Description

Given a project containing a widget and this in index.xml:

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

The widget receives an arguments object containing two extra null values which presumably correspond to the ItemTemplate tags. Those should be removed by the Ti.UI.ListView.js parser. Generated code without this change:

$.__views.__alloyId0 = Alloy.createWidget("foo", "widget", {
    id: "__alloyId0",
    children: [ , , $.__views.__alloyId1 ],
    __parentSymbol: $.__views.index
});

Using child views of Widget other than ListView (such as using a pair of Views) does not pass those null values via the children array. Workaround: reference the children array like this:

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

Feon Sua Xin Miao 2014-08-04 PR: https://github.com/appcelerator/alloy/pull/499 Test app: https://github.com/feons/alloy/tree/ALOY-1064/test/apps/testing/ALOY-1064 Functional Test: 1. Compile test app on iOS 2. There should be no null values for widget's children property. The generated code should look like this: 128 $.__views.__alloyId0 = Alloy.createWidget("foo", "widget", { 129 id: "__alloyId0", 130 children: [ $.__views.__alloyId1 ], 131 __parentSymbol: $.__views.index 132 });
