[S2]struts2 validation error message problem

Tue, 17 Jul 2007 02:37:22 -0700 

hi, this is my first web-based project using struts2.0. I met a problem when
using the validation . It seems the error message haven't been cleared and
each time I submit the form, then the error message was added after the
previous error message, it means if i submit 10 times, then there will
display 10 error message, 10 of the same. any help would be appreciated.

struts-app.xml:
<package name="account" namespace="/" extends="default">
    <global-results>
           <result name="input">jsp/account/account.jsp</result>
    <result name="login_input">index.jsp</result>
       </global-results>

       <action name="account_save" method="save" class="AccountAction">
    <interceptor-ref name="myStack"/>
 </action>
 <action name="account_*" method="{1}" class="AccountAction" >
  <result name="create_success">/jsp/message.jsp</result>
    <result name="create_failed">/jsp/message.jsp</result>
    <result name="delete_success">/jsp/message.jsp</result>
    <result name="wellcome">test.jsp</result>
    <result name="list">jsp/account/userList.jsp</result>
    <result name="account_role">jsp/account/userRole.jsp</result>
    <result name="person_input">jsp/account/personSet.jsp</result>
 </action>
</package>

AccountAction:
Jsp:
validation.xml

see the files.

the error message look just like this;
*string length shoule be 4-10 *string length shoule be 4-10 *string length
shoule be 4-10 *string length shoule be 4-10 *string length shoule be
4-10 *string
