Struts2.0 表单中用到select标签提交时出错
2008-11-13 21:44
405 查看
在表单用中到了select标签，页面初始化时一切正常，select也正常初始化
可是当我提交时就出现如下错误：
严重: Servlet.service() for servlet jsp threw exception
tag 'select', field 'list', name 'functions.typeId': The requested list key '%{types}' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]
在应用中我用到两个Action,两个jsp页面
一个FunctionsAction，一个FunctionstypeAction
一个add_function.jsp,一个add_functions_success.jsp
具休流程是我从FunctionstypeAction中获取一个functionstypes的List
用来初始化add_function.jsp中的select标签，
然后把表单提交给FunctionsAction中的insert方法
add_function.jsp初始化是正常的，
但是点提交到FunctionsAction的时候页面空白
我看了一下源文件，页面只执行了一部分，
代码如下：

我现在的感觉是List是不是只能从同一个Action中调出,也只能提交到同一个Action????

这个错误应该是由于提交的时候，校验出错，返回到提交页面，然后这个时候是直接返回到jsp页面，action没有执行，造成取list的时候没有值，当然不用校验就不会出错了，看看你的校验代码，或者修改action类就行了。
引用
FunctionstypeAction:
代码

不过问题过去了，感觉select还是满有用的，呵呵...

我觉得很有可能是
Java代码

我在webwork中刚开始也遇到同样的问题
soardragon 2007-06-23 回复
movingboy 多谢你的回答!
今天把action包中的一个验证配置给删了，结果就正常了，
顺便问一个
如果Action的验证配置没有起别名的话是不是会过滤掉所有的东西？
我删的那个配置文件是xxxAction-validation.xml
如果我要针对insert方法过滤是不是要这样写
xxxAction-insert-validation.xml?

在JSP中不使用<s:set>标签，直接按下面写试试：
Java代码
<%@page language="java" pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<s:textfield name="functions.name" label="职能名称"/>
<s:submit value="添加"/>

另外说一句：list是可以从其它action中取的，
可是当我提交时就出现如下错误：
严重: Servlet.service() for servlet jsp threw exception
