javascript - Uncaught Error : no data returned for views/AgeTypes.fragment.xml

Question

我的 AgeTypes.fragment.xml 就像:

<core:FragmentDefinition
    xmlns="sap.m"
    xmlns:core="sap.ui.core">

    <ResponsivePopover
        id="popAgeTypes" class="sapUiPopupWithPadding"
        afterClose="onAgeTypesClosed"
        placement="Auto" showHeader="false" >
        <beginButton>
            <Button text="OK" press="onAgeTypeChanged" /> 
        </beginButton>
        <content>

        <List id="ageTypes" mode="MultiSelect"
            includeItemInSelection="true"
            items="{...}">

            <items>...</items>
        </List>
        </content>
    </ResponsivePopover>
</core:FragmentDefinition>

在我看来，有一个按钮可以在按下时打开此弹出窗口片段。我的按钮 xml 是:

<m:Button id="ageTypesId" text="Ages" icon="sap-icon://person-placeholder"
                press="onAgeTypeSelect"/>

在我的 Controller 中:

//this method is triggered when user press button.
onAgeTypeSelect: function(oEvent){
    this.popAgeTypes = sap.ui.xmlfragment( App.ComponentName + ".views.AgeTypes", this);
    this.getView().addDependent(this.popAgeTypes);
    this.popAgeTypes.openBy(oEvent.getSource());
},

//when user select items from responsive popover list item
onAgeTypeChanged: function(oEvent) {
    //taking selected items and doing some business.
    this.popAgeTypes.close();
    this.popAgeTypes.destroy();
},

//and this code is triggered when afterClose method of Responsive popover work
onAgeTypesClosed : function(oEvent){
    if (this.popAgeTypes) {
        this.popAgeTypes.destroy();
    }
}

最奇怪的是我能够打开这个响应式弹出窗口几分钟或更长时间。在那之前，我可以正确打开和关闭它，但几分钟后我无法打开它，并且出现 未捕获错误:没有为 .../views/AgeTypes.fragment.xml 返回数据 错误。我用谷歌搜索了它，但找不到任何有用的信息。

我正在测试，如果您在 Chrome 48.0.2564.97 中使用 UI5 应用之前打开 Gmail 帐户，则 x.fragment.xml 不会给出错误。
