iview form 表单的怪异小BUG

当同一个弹窗中的表单重复利用时：

我原先的代码逻辑是：

 1 <Form :label-width="100" class="mt20" ref="changeParam" :rules="ruleValidate"  :model="changeParam">
 2             <Row>
 3               <Col span="22">
 4                 <FormItem label="课程">
 5                   <Input v-model="info.f_lesson_name" disabled style="200px;"></Input>
 6                 </FormItem>
 7               </Col>
 8             </Row>
 9             <Row v-if="info.teacher_id > 0">
10               <Col span="22" class='pr'>
11                 <FormItem label="原授课老师">
12                   <Input v-model="info.f_teacher_id" disabled  style=" 200px"></Input>
13                 </FormItem>
14               </Col>
15             </Row>
16             <Row>
17               <Col span="22" class='pr'>
18                 <FormItem v-if="info.teacher_id > 0" label="新授课老师" prop="teacher_id">
19                   <i class="clearSelect" v-if="changeParam.teacher_id"  @click="clearSelect">X</i>
20                   <Select
21                     style=" 200px"
22                     v-model="changeParam.teacher_id"
23                     :disabled="changeParam.teacher_id ? true: false"
24                     placeholder="请搜索后选择老师"
25                     filterable
26                     remote
27                     :remote-method="searchTeacher">
28                     <Option v-for="(item,key) in teacherList" :value="item.userid" :key="key"> {{item.f_campus ? item.f_campus: item.f_city }}-{{item.realname}}</Option>
29                   </Select>
30                 </FormItem>
31                 <FormItem v-else label="授课老师" prop="teacher_id">
32                   <i class="clearSelect" v-if="changeParam.teacher_id"  @click="clearSelect">X</i>
33                   <Select
34                     style=" 200px"
35                     v-model="changeParam.teacher_id"
36                     :disabled="changeParam.teacher_id ? true: false"
37                     placeholder="请搜索后选择老师"
38                     filterable
39                     remote
40                     :remote-method="searchTeacher">
41                     <Option v-for="(item,key) in teacherList" :value="item.userid" :key="key"> {{item.f_campus ? item.f_campus: item.f_city }}-{{item.realname}}</Option>
42                   </Select>
43                 </FormItem>
44               </Col>
45             </Row>
46             <Row>
47               <Col span="22" class='pr' v-if="info.teacher_id > 0">
48                 <FormItem label="理由" prop="reason_service" style="font-size: 14px;">
49                   <Select v-model="changeParam.reason_service" style="200px;">
50                     <Option v-for='(item,key) in reason_service' :value="key" :key='key'>{{item}}</Option>
51                   </Select>
52                 </FormItem>
53               </Col>
54             </Row>
55             <Row v-if='changeParam.reason_service == 99'>
56               <Col span="22" class='pa'>
57                 <FormItem label="备注" prop="remark">
58                   <template>
59                     <Input type="textarea" v-model="changeParam.remark" :autosize="{minRows: 2,maxRows: 5}"
60                            placeholder="备注" style="300px;"></Input>
61                   </template>
62                 </FormItem>
63               </Col>
64             </Row>
65           </Form>

更改后：

 1 <Form :label-width="100" class="mt20" ref="changeParam" :rules="ruleValidate"  :model="changeParam">
 2             <Row>
 3               <Col span="22">

58                 <FormItem label="备注" prop="remark">

62                   </template>
63                 </FormItem>
64               </Col>
65             </Row>
66           </Form>

具体原因我目前不清楚，但确实是把判断写在row中了，当更改后，就可以了；让自己下次注意。并且找时间找到为啥
