我想在没有子故事的投资组合项下的“我的用户故事仪表板”上创建一个自定义网格。

My Dashboard 上带有 Object: PortfolioIetm Feature 的自定义网格并查询 UserStories.DirectChildrenCount = 0 将产生此错误：

Could not parse: Attribute "UserStories" on type PortfolioItems is not allowed in query expressions.

这是一个自定义 App SDK 2 应用程序，它使用 DirectChildrenCount = 0 的用户故事构建功能网格。它访问每个功能的故事集合

var stories = feature.getCollection('UserStories');

但仅使用那些没有孩子的故事填充网格。这是可以粘贴到自定义选项卡中的完整 App.html 代码：

    <!DOCTYPE html>

<head>
    <title>GridExample</title>

    <script type="text/javascript" src="/apps/2.0rc1/sdk.js"></script>
