struts2 又出问题

[sungirlzcy]

我写了俩checkbox
我的意思是想让它被选择的时候就显示1，不选择就显示0，
可是，当我不选择的时候就出这个Invalid field value for field "role.moduleFlag".
这是咋整啊？
要贴代码吗？

校验的问题

你页面传的参数,跟model 接收的参数类型不匹配.
检查下你不选择的时候,model中的moduleFlag值是什么

最好有代码~

<s:textfield name="role.roleName" /></td>

<s:checkbox name="role.moduleFlag" fieldValue="1"/>

当你选择的时候,struts2会把值赋给role.moduleFlag,即表单中的1
如果你不选择的时候,struts2会把role.moduleFlag解析为
role.moduleFlag=false

由于你role中定义的moduleFlag为int,所以报Invalid field value for field "role.moduleFlag"

[cust28]

表单中<s:checkbox name="role.moduleFlag" fieldValue="1"/>
换成<input type="checkbox" name="role.moduleFlag" value="1" />
就不会报那个错误了

[sungirlzcy]

好了，太感谢你了，老感谢了，我一辈子都会记得你的，
呵呵
可是为什么用标签那个不行啊
真的太感谢你了

[cust28]

估计是 struts2自定义标签就那么设计的
有兴趣的话,可以看看标签的源码
给分啊~ 呵呵
