Hi ,
Iam beginner in Struts2,
iam having query on  Execute and wait Interceptor ,

my code flow is like this

Login->Wait Interceptor->Menu/Fail.jsp

I added Interceptor in Struts.xml

 
     <action name="doLogin" class="validatorlogin.Login">
            <interceptor-ref name="completeStack" />
            <interceptor-ref name="execAndWait" />                  
            <result name="wait">Wait.jsp</result>
            <result name="success">menudemo.jsp</result>
            <result name="error">Fail.jsp</result>
        </action>



When i run the project,
After Submitting Login.jsp ,Wait.jsp is rendered after that i[b]t throws
Null pointer Exception instead of Menu.jsp[/b]



With reference to
http://struts.apache.org/2.0.6/docs/execute-and-wait-interceptor.html
http://struts.apache.org/2.0.6/docs/execute-and-wait-interceptor.html 
 i tried adding delay before the wait page but i get Compilation error 
  
  <interceptor-ref name="execAndWait">
        1000
        50
    <interceptor-ref>


Could any one please help me out ,
Thanks in advance,
Arvin
