Titanium Alloy 无法访问三级嵌套对象

Titanium Alloy can't access third level nested object

我 运行 遇到了 Titanium Alloy 的问题。我似乎无法从控制器访问 XML 中声明的 3d 级嵌套对象。

这是XML中的布局:

<Alloy>
    <Collection src="reportDetails"/>
    <Window class="container" title="Update Report Details" onClose="cleanup" >

        <View id="labels">          
            <TextArea id="jobTitle" class="title bold" editable="false"></TextArea>         
            <View class="jobTitleSecondPart" >
                <Label class='bold'>last date od service: </Label>
                <Label id="jobDate" class="stickLeft"></Label>
                <Label class='bold'>Job ID: #</Label>
                <Label id="jobId" class="stickLeft"></Label>
            </View>
        </View>
        <ActivityIndicator id="busy"></ActivityIndicator>
        <View height="Titanium.UI.FILL">
            <ScrollView  id="scrollIns" layout="vertical" dataCollection="reportDetails" dataFilter="filterFunction" height="Titanium.UI.FILL">
                <View id="instruction"> <!-- ***I am trying to access this object in the controlle***r -->
                    <Label class="title bold black">Agent Instructions :</Label>
                    <Label platform="android" id="jobInstruction" html="{agentInstructions}" class="black"   height="Titanium.UI.SIZE" />
                    <WebView platform="ios" id="jobInstruction" html="{agentInstructions}" class="black" touchEnabled="false" height="Titanium.UI.SIZE" />
                </View>
                <View id="comment">
                    <Label class="title bold black">Agent Comment :</Label>
                    <Label id="jobComment" class="black" text="{reportComment}"></Label>
                </View>
                <Require src="reportImageGallery" images="{images}"/>
            </ScrollView>
            <View id="buttons">
                <Button id="btnInsert" class="bold" onClick="showInsertReport">Insert Update Reports</Button>
            </View>
        </View>

    </Window>
</Alloy>

这是来自控制器的代码行:

$.instruction.visible = false;

这是它给我的错误:

留言="undefined is not an object (evaluating '$.instruction.visible = false')";

@Turtle 是正确的,数据绑定父元素内的 ID(使用 dataCollection)不能用于通过 $.<id> 到达它们,因为会有不止一个实例。
