钛合金ListView XML未捕获的TypeError:对象#< UI>没有方法'createTemplates' [英] Titanium Alloy ListView XML Uncaught TypeError: Object #<UI> has no method 'createTemplates'

问题描述

我是钛合金的新手，请原谅我缺乏理解.

I am new to Titanium, so excuse my lack of understanding.

即使我尝试使用sdk 3.2版(在tiapp.xml中具有sdk版本:3.2.0.v20130801162445)，当我尝试使用具有上述xml的视图时，也会出现此错误:[ERROR] [V8Exception(615)]在Alloy/controllers/feed.js处发生异常:22:未捕获的TypeError:对象#没有方法'createTemplates'

Even though I am using sdk version 3.2 (have sdk-version: 3.2.0.v20130801162445 in my tiapp.xml) when I try and have a view that uses the xml above I get this error: [ERROR][V8Exception( 615)] Exception occurred at alloy/controllers/feed.js:22: Uncaught TypeError: Object # has no method 'createTemplates'

我削减了所有代码，以便feed.js文件只是:

I cut down all my code so that the feed.js file is just:

function loadMoreBtnClicked(_event) {
    alert('not implemented yet');
}


function createListView(_data) {
    // this is pretty straight forward, assigning the values to the specific
    // properties in the template we defined above
    var items = [];
    for (var i in _data) {

        // add items to an array
        items.push({
            template : "template1",            // set the template
            textLabel : {
                text : _data[i].name           // assign the values from the data
            },
            pic : {
                image : _data[i].pic_square    // assign the values from the data
            }
        });
    }

    // add the array, items, to the section defined in the feed.xml file
    $.section.setItems(items);

}

alert('feed loaded');

XML位于feed.xml中，如下所示:

The XML is in feed.xml and looks like this:

<Alloy>
    <Window class="container" formFactor="handheld">
        <ListView id="list" defaultItemTemplate="template1">
            <Templates>
                <ItemTemplate name="buttonItem" height="Ti.UI.SIZE">
                    <!-- will use this in the next blog post -->
                    <Button id="loadMoreBtn" onClick="loadMoreBtnClicked">Load More</Button>
                </ItemTemplate>
                <!-- main template for displaying the list items -->
                <ItemTemplate  id="template1" name="template1"  class="template1">
                    <ImageView id="pic"  bindId="pic" class="imageThumb"/>
                    <View id="textContainer">
                        <Label id="textLabel" bindId="textLabel" class="title"/>
                    </View>
                </ItemTemplate>
            </Templates>
            <!-- we only have one section and the items are contstucted using template1 -->
            <ListSection id="section" >
                <ListItem template="template1" />
            </ListSection>
        </ListView>
    </Window>
</Alloy>

我仍然收到错误消息(仅使用XML，除了运行警报外，没有任何实际的控制器代码).如果将ListView XML从feed.xml文件中拉出，则会触发警报，当我将ListView XML放回时，会出现上述错误.

I still get the error (just using the XML with no actual controller code other than the alert running). If I pull the ListView XML out of the feed.xml file the alert fires, when I put the ListView XML back in I get the Error above.

我正在尝试使用此示例中的代码: https://gist.github.com/aaronksaunders/5896390 但真的不能说出我在想什么吗?

I am trying to use code from this example: https://gist.github.com/aaronksaunders/5896390 but cant really tell what I am missing?

谢谢！-詹姆斯

推荐答案

发现了问题所在，我的问题与没有支持XML中的ListView模板所需的合金的更新版本有关.我需要在Windows的命令行中运行此命令:"npm install -g alloy@1.2.0-alpha"(不带引号).之后，我就能使用XML的ListView模板，如上所示.

found out what the issue was, my problem had to do with not having the updated version of alloy that is needed to support the ListView Templates in XML. I needed to run this at the command line in Windows: "npm install -g alloy@1.2.0-alpha" (without quotes). After that I was able to use ListView templates in XML as shown above.
