Steps to reproduce

等待一段时间，看显示结果

What is expected?

我希望1s之后，SchemaField.String内部渲染的input组件，value从init -> next

What is actually happening?

SchemaField.String内部渲染的input组件，组件不变化

Package

@yiyunwan 我知道可以用scope，用scope的话不用observer组件也是可以的，像这样 https://codesandbox.io/s/confident-banach-zfvfjk

export default () => {
  setTimeout(() => {
    dataSource.value = "next";
  }, 1000);
  return (
    <FormProvider form={form}>
            <SchemaField>
              <SchemaField.String
                name="input"
                x-component="Input"
                x-value="{{dataSource.value}}"
              />
            </SchemaField>
    </FormProvider>
  );
};

但我理解Observer下的响应式变量更新时，会再次渲染它底下的函数组件，这里SchemaField.String这种case不会更新是为什么呢？

SchemaField在初次加载会初始化字段模型，仅在第一次生效，后续并不会再对字段模型重新赋值了，状态管理移交至字段模型内部，本质跟schema没区别的，这点跟常规组件理解不太一样
