传递给子组件时动态组件不呈现

Question

我正在尝试将组件构造函数传递给子组件，但是当我这样做时，我收到一条错误消息：Assertion Failed: A helper named 'parent.section' could not be found

//parent-form.js
form-component as |f|
  ...
  child-component f=f

//child-component.js
f.group as |g|
  ...

//form-component.js
with (hash group=(component 'form-section-component')) as |h|
  yield h

奇怪的是，如果我延迟parent.group调用，一切正常。例如：

//child-component.js
if isShowingFormSection
  f.group as |g|
    ...

当isShowingFormSection更改为true时，parent.group会被调用并呈现正常。

这是否意味着模板在组件准备好之前尝试实例化组件？
