struts中的下拉框问题

[guanwei10]

各位高手大大们：
小弟在做个用户信息添加，里边有个区域选择这个下拉框，这个下拉框我是动态从另一张表中得到的数据
现在的问题是 我能够显示用户添加页面 而且也能在下拉框中得到 区域的信息
但是 只要我一点确定按钮 他就报错了！

我给出form的属性

private AreaBaseInfo areaBaseInfo;

JSP

<html:select property="areaBaseInfo">
          		<logic:present name="areaList">
          			<html:options collection="areaList" labelProperty="areaName" property="areaId"/>
          		</logic:present>
          	</html:select>

错误信息

[Quote=引用 5 楼 xiaojing_tkgame 的回复:]
private AreaBaseInfo areaBaseInfo;

和
<html:select property="areaBaseInfo">
                  <logic:present name="areaList">
                      <html:options collection="areaList" labelProperty="areaName" property="areaId"/>
                  </logic:present>
              </html:select>

你要选择的类型不匹配，选择的应该是string类型的areaBaseInfo在action的时候怎么赋值啊

我这个是实体类呀，要是String的那么

没人。。。

错误原因：jsp页面中表单标记库类型与form表单的enctype属性值不匹配。
解决方法：设置正确的enctype属性值。

[vincent201201]

<html:select name="xxxForm" property="areaBaseInfo">
<html:options collection="areaList" property="areaId" labelProperty="areaName"/>
</html:select>

试试

[老张-AI]

<html:select property="file.joy.joyId" style="width: 200px">
							<html:options collection="joyList" labelProperty="joyName" property="joyId"/>
						</html:select>

给你个例子
用这个标签

[xiaojing_tkgame]

private AreaBaseInfo areaBaseInfo;

和
<html:select property="areaBaseInfo">
<logic:present name="areaList">
<html:options collection="areaList" labelProperty="areaName" property="areaId"/>
</logic:present>
</html:select>

你要选择的类型不匹配，选择的应该是string类型的

[gukuitian]

private String areaBaseInfo;

[cbdhxka]

private AreaBaseInfo areaBaseInfo;
改为private String areaBaseInfo;
