------------------------

             Summary: buttons with name="method:METHODNAME" sometimes ignore global-allowed-methods
defined in struts.xml
                 Key: WW-4918
                 URL: https://issues.apache.org/jira/browse/WW-4918
             Project: Struts 2
          Issue Type: Bug
          Components: Core Actions
            Reporter: Nate


I have the following action (slightly edited to remove identifying info):

<action name="userEdit" class="struts2package.actions.user.UserEditAction">
 <interceptor-ref name="defaultStack">
 <!-- Exclude the dojo parameters, the displaytag sorting/paging parameters and the resetSelectedVersion
parameter-->
 <param name="params.excludeParams">dojo\..*,struts\..*,d-\d+?-[sop],..*multiselect..*</param>
 <param name="authorizationInterceptor.authorizationRole">globalAdmin</param>
 </interceptor-ref>
 <interceptor-ref name="token">
 <param name="excludeMethods">input,back,refresh,cancel,browse</param>
 </interceptor-ref>
 <interceptor-ref name="struts2ActionErrorInterceptor"/>
 <interceptor-ref name="struts1ErrorMessageInterceptor"/>
 <result name="input">/jsp/user/userEdit.jsp</result>
 <result name="error" type="redirectAction">
 <param name="actionName">displayUserEdit.action</param>
 </result>
 <result name="redirectToUserOverview" type="redirectAction">
 <param name="actionName">userOverviewRetained.action</param>
 <param name="globalInfo">info.transaction_success</param>
 </result>
 <result name="success">/jsp/user/userEdit.jsp</result>
 <result name="back" type="redirect">${backUrl}</result>
 </action>

And the following global allowed methods:

<global-allowed-methods>update,execute</global-allowed-methods>

And these buttons:

 

<div class="buttonRow">
<%-- The 'Save' button --%>
 <input value="Save"
 type="submit" class="button" name="method:update" />

<%-- The 'Refresh' button --%>
 <input value="Refresh"
 type="submit" class="button" name="method:refresh"
 id="refreshButton" />

<%-- The 'Back' button --%>
 <input value=Back"
 type="submit" class="button" name="method:back" />
 </div>

 

As you can see, the update method is defined in the global-allowed-actions list, but the refresh
and back methods aren't. However, what happens is that the update button with the update method
works and updates the user, the refresh action shows the "method is not allowed" error screen
and doesn't update the user(both as expected since update is defined in the allowed methods
and refresh isn't), but the back button DOES actually work even though it's not explicitly
defined in the global-allowed-methods section.

 

I'm trying to understand why out of 2 methods both not defined as allowed-methods, one is
correctly blocked  as "not allowed" while the other is still allowed through. If I add ",refresh"
to the global-allowed-methods and restart tomcat, the refresh button ends up working afterwards
as expected, and the back button stays functional. I don't use the plugin that adds the Allowed
Methods annotation, and this same situation also happens when using s:submits with method="back"
defined, even if there is already a method defined on the action entry in struts.xml.
