这个案例来自这篇博客《Angular: Nested template driven form》。 在使用表单校验的时候我们也遇到了一样的问题。如图10所示,由于某些原因我们把三个字段的地址封装成一个组件以供复用。 图10 把表单的地址三个字段封装成一个子组件 这时候我们会发现报错了,ngModelGroup需要一个host内部的ControlContainer,也就是ng...
To add more information, in my case the error only happens with nested FormGroups. I create an entire new form each time the user changes a field, some controls are the same and other change. There is one that is a FormGroup where the name does not change, but the FromControls inside...
