Fieldcontainer 错误地显示在工具栏中，标签对齐顶部

Question

当您放置 labelAlign: 'top' 时，FieldContainer 无法正确显示。

找到我的小提琴：https://fiddle.sencha.com/#fiddle/1c2s 我创建了一个基于字段容器的自定义字段。 如果将窗口调整为更小的尺寸，您会看到文本字段将位于 fieldContiner 上方。

关于如何解决这个问题的任何想法？任何解决方法？ 我已经尝试了几种方法，但我很挣扎……我现在无法采取行动来改变这一点…… 我肯定需要解决这个问题。

提前致谢

Answer 1

看起来确实像错误，但有一种很简单的方法可以让它工作 - 只需将 minHeight: 65 设置为您的 url 字段。

Answer 2

我很确定我找到了答案。 build src 和 doc 不匹配！

如果您检查文件src/layout/component/field/FieldContainer.js 的构建源代码，您会注意到它与文档不对应（尤其是缺少一些方法，例如calculateOwnerHeightFromContentHeight）。

注意：这已在 ExtJs 6.2.0 中修复

建议覆盖以解决此问题：

/**
 * Override to fix componentLayout wrong calculation of height when labelAlign='top'
 *
 * See post forum:
