- [ ] I have searched the [issues](https://github.com/vueComponent/ant-design-vue/issues) of this repository and believe that this is not a duplicate. ### What problem does this feature solve? 之前在antdv2.x版本使用useform的validate方法能正常校验,升级antdv3.0.0-alpha.14后无法正常提示用户错误信息 ### What does the proposed API look like? antdv3.0.0-alpha.14、vue3.2.0 <!-- generated by issue-helper.
