working flow of edit thread:
 .viewThread : 用户点击“修改”链接(链接里提供ThreadID)，执行 editThreadLink.go
 .EditThreadLinkAction : 取该帖子信息，若成功，转向 editThead.jsp
 .editThread.jsp : 用户修改帖子内容，点击提交，执行 editThread.go
 .EditThreadAction : 到数据库修改该帖子，若成功，转向 viewThread.go

.action editThreadLink:
	<action	path="/editThreadLink"
	              type="org.redsoft.forum.web.EditThreadLinkAction"
	              validate="false">
	<forward name="logon"	path="/logon.jsp"/>
	<forward name="success"	path="/editThread.jsp"/>
	<forward name="error"	path="/error.jsp"/>      	
	</action>
	
.action editThreadLink:

	<action	path="/editThread"
	              type="org.redsoft.forum.web.EditThreadAction"
                  name="EditThreadForm"
                  input="/editThread.jsp"
                  scope="request"
	              validate="true">
	<forward name="logon"	path="/logon.jsp"/>
	<forward name="success"	path="/viewForum.go"/>
	<forward name="error"	path="/error.jsp"/>      	
	</action>

form-bean EditThreadForm
<form-bean name="EditThreadForm" type="org.redsoft.forum.web.EditThreadForm"/>

.问题：
 修改完帖子后如何回到原来的 viewThread.jsp
 action name 不统一：editThreadLink, EditThread; post, postThread; account, editAccount
 bug:用户可以自己写 url 代码来修改别人的帖子，所以在 editThreadLink 中要检查是不是作者。
 bug:user can edit subject to null :(
  error.thread.notAuthor=<li>You are not the author of the thread</li>
