title: Cannot exclude method in struts2 interceptor
body: <p>I am having the opposite problem of the fellow in this question:
  <a href="https://stackoverflow.com/questions/8116076/struts-2-excluding-method-from-validation-from-just-the-defaultstack-intercepto">Struts 2: excluding method from validation from just the defaultStack interceptor</a></p>
  
  <p>The above question involved all methods being excluded, my issue is that no methods are being excluded!</p>
  
  <p>I'm trying to get my authenticationInterceptor to ignore the showLogin method of my LoginAction:</p>
  
  <pre><code>&lt;interceptors&gt;
      &lt;interceptor name="authorizationInterceptor" class="org.companyname.struts.interceptor.AuthorizationInterceptor"/&gt;
      &lt;interceptor-stack name="appDefault"&gt;
          &lt;interceptor-ref name="authorizationInterceptor"/&gt;
          &lt;interceptor-ref name="defaultStack"&gt;
              &lt;param name="exception.logEnabled"&gt;true&lt;/param&gt;
              &lt;param name="exception.logLevel"&gt;ERROR&lt;/param&gt;
          &lt;/interceptor-ref&gt;              
      &lt;/interceptor-stack&gt;
  &lt;/interceptors&gt;
  &lt;default-interceptor-ref name="appDefault" /&gt;
  
  &lt;action name="loginInitial" class="org.companyname.struts.action.LoginAction" method="showLogin"&gt;
      &lt;interceptor-ref name="appDefault"&gt;
          &lt;param name="authorizationInterceptor.excludeMethods"&gt;showLogin&lt;/param&gt;             
      &lt;/interceptor-ref&gt;
      &lt;result name="success"&gt;/login.jsp&lt;/result&gt;                      
  &lt;/action&gt;
  </code></pre>
  
  <p>However, each time I forward to loginInitial, the interceptor grabs it, even though my showLogin method is being excluded.  </p>
  
  <p>I've checked for naming issues, and have tried putting several different values in the interceptor-ref within the action, and nothing seems to work.</p>
  
  <p>What's the proper way to skip the authorizationInterceptor when I forward to loginIntial?</p>
