Barista: [Expandable Section] 布尔强制无法对“expanded”属性正常工作

创建于 2020-08-10 · 13评论 · 资料来源: dynatrace-oss/barista

错误报告

你好团队！似乎expanded属性不适用于强制，但如果设置为： [expanded]="true"则可以正常工作。这很长时间运行良好，但最近停止工作并阻止我的一个生产页面正确呈现： https :

预期行为

我希望以下内容能像往常一样工作：
<dt-expandable-section expanded>

当前行为

TypeError: Cannot set property 'expanded' of undefined
    at DtExpandableSection.set expanded [as expanded] (dynatrace-barista-components-expandable-section.js:79)
    at Object.ngOnChangesSetInput [as setInput] (core.js:26879)
    at setInputsFromAttrs (core.js:13039)
    at instantiateAllDirectives (core.js:12752)
    at createDirectivesInstances (core.js:11989)
    at Module.ɵɵelementStart (core.js:21043)
    at AppComponent_Template (app.component.html:1)
    at executeTemplate (core.js:11949)
    at renderView (core.js:11735)
    at renderComponent (core.js:13244)

可能的解决方案

<dt-expandable-section [expanded]="true">

重现步骤

克隆： https :

二手版本：

@dynatrace/barista-components ：7.6.0

非常感谢您的辛勤工作！

嘿@areknow非常感谢你报告这个，但我无法在 stackblitz 中重现这个
https://stackblitz.com/edit/github-yp9pwy?file=src/expandable -section/expandable-section-default-example/expandable-section-default-example.html

此外，当我查看代码时，使用了coerceBooleanProperty 。 🤔

您确定正确使用组件吗？

https://github.com/dynatrace-oss/barista/blob/master/libs/barista-components/expandable-section/src/expandable-section.ts#L76

  @Input()
  get expanded(): boolean {
    return this._panel.expanded;
  }
  set expanded(value: boolean) {
    this._panel.expanded = coerceBooleanProperty(value);
    this._changeDetectorRef.markForCheck();
  }

嗨@lukasholzer！我也无法在 stackblitz 中重现，所以我创建了一个最小的 repo。这可能表明 ivy 存在视图渲染器未发生的问题。您是否能够克隆存储库并查看控制台错误？

areknow 于 2020-08-11

你好@lukasholzer ，
我还可以使用指令的速记符号重现该问题。

@areknow您能否尝试在您的应用中使用可扩展的材料并比较其行为。我很好奇我们是否有一些常春藤兼容性的编译问题。这将是一个最小的设置https://stackblitz.com/edit/angular-rubmxc?file=src/app/expansion -steps-example.html

@areknow我克隆了你的 repo 做了一个 npm 安装，现在一个 ng 服务：

除此之外，请更新highcharts版本并删除@types/highcharts

lukasholzer 于 2020-08-12

@ffriedl89我导入了MatExpansionModule并将组件标记添加到项目中，它使用速记指令符号运行得非常好。

@lukasholzer我删除了@types/highcharts并将highcharts更新

@areknow我把不可复制的标签放在上面，因为当我想为应用程序提供服务时看到上面的错误。所以我无法为应用程序提供服务。

让你的回购为我运行是不可能的。

我做的步骤：

git clone ...
npm install
ng serve

lukasholzer 于 2020-08-12

@lukasholzer我已经在三台不同的机器上运行了 repo。不知道是什么问题，这是一个超级基础的项目🤔
@josecolella @toddbaert也运行了 repo 并看到了同样的问题。
