aem - AEM 6.2 - 只有一个输入字段的触控 UI / Granite UI 不起作用

Question

如果我正在构建一个只有一个输入字段的对话框，则该对话框将不会显示在作者中。

这是我的示例代码（headline_dialog.xml）：

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
          xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
          jcr:primaryType="nt:unstructured"
          sling:resourceType="cq/gui/components/authoring/dialog">
    <content
            jcr:primaryType="nt:unstructured"
            sling:resourceType="granite/ui/components/foundation/container">
        <layout
                jcr:primaryType="nt:unstructured"
                sling:resourceType="granite/ui/components/foundation/layouts/fixedcolumns"/>
        <items jcr:primaryType="nt:unstructured">
            <column
                    jcr:primaryType="nt:unstructured"
                    sling:resourceType="granite/ui/components/foundation/container">
                <items jcr:primaryType="nt:unstructured">
                    <text
                            jcr:primaryType="nt:unstructured"
                            sling:resourceType="granite/ui/components/foundation/form/textarea"
                            fieldLabel="Überschrift Text"
                            name="./text"
                            fieldDescription="Bitte pflegen Sie hier den Textinhalt Ihrer Überschrift."/>
                </items>
            </column>
        </items>
    </content>
</jcr:root>

这是我们将在作者中看到的：

如果我现在向对话框添加第二个输入字段。对话框将显示在作者中：

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
          xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
          jcr:primaryType="nt:unstructured"
          sling:resourceType="cq/gui/components/authoring/dialog">
    <content
            jcr:primaryType="nt:unstructured"
            sling:resourceType="granite/ui/components/foundation/container">
        <layout
                jcr:primaryType="nt:unstructured"
                sling:resourceType="granite/ui/components/foundation/layouts/fixedcolumns"/>
        <items jcr:primaryType="nt:unstructured">
            <column
                    jcr:primaryType="nt:unstructured"
                    sling:resourceType="granite/ui/components/foundation/container">
                <items jcr:primaryType="nt:unstructured">
                    <text
                            jcr:primaryType="nt:unstructured"
                            sling:resourceType="granite/ui/components/foundation/form/textarea"
                            fieldLabel="Überschrift Text"
                            name="./text"
                            fieldDescription="Bitte pflegen Sie hier den Textinhalt Ihrer Überschrift."/>
                    <example
                            jcr:primaryType="nt:unstructured"
                            sling:resourceType="granite/ui/components/foundation/form/textfield"
                            fieldLabel="Dummy"
                            name="./example"
                            value="exampletext"
                            disabled="true"
                            fieldDescription="Dummy Text"/>
                </items>
            </column>
        </items>
    </content>
</jcr:root>

现在我们正确地看到了对话框：

这是新触摸用户界面中的错误吗？还是我在第一个对话框 XML 文件中出错了？
