Steps to reproduce
<a-select v-decorator="['vefiry', {initialValue:0}]" placeholder="认证状态">
<a-select-option value="0" key="0">全部</a-select-option>
<a-select-option value="1" key="1">已认证</a-select-option>
<a-select-option value="2" key="2">未认证</a-select-option>
</a-select>
在表单中,使用v-decorator设置select的initialValue为0
What is expected?
select显示“全部”
What is actually happening?
select显示“0”
即使在mounted中使用setFieldsValue为“0”显示了“全部”,resetFields之后还是会显示0
