Subject [jira] [Created] (WW-3965) Double bang on form action
Date Wed, 16 Jan 2013 16:54:13 GMT
Greg Huber created WW-3965:

             Summary: Double bang on form action
                 Key: WW-3965
             Project: Struts 2
          Issue Type: Bug
          Components: Core Actions
    Affects Versions: 2.3.8
         Environment: Centos Apache/tomcat with mod_jk
            Reporter: Greg Huber
            Priority: Minor


I sometimes use the dynamic method invocation on the form action for submitting and have noticed
for a while now, that there is a double bang on the compiled page: 

eg. If I use action="license!member" on the compiled page I get

on the jsp:

<s:form action="license!member" >


<form method="post" action="/events/license!member!member.action" id="license!member" name="license!member">

It only seems to be on the form tag though.

Have traced it to DefaultActionMapper, line 539.  It needs to check to make sure there is
no bang already before adding another one, ie follow existing logic in other methods.

if (null != mapping.getMethod() && !"".equals(mapping.getMethod())) {

This seems to have fixed it:

//if (null != mapping.getMethod() && !"".equals(mapping.getMethod())) {
if (allowDynamicMethodCalls) {
if (null != mapping.getMethod() && !"".equals(mapping.getMethod())) {
// handle "name!method" convention.
name = mapping.getName();
if (name.indexOf("!") == -1) {
// Append the method as no bang found
} else {
if (null != mapping.getMethod() && !"".equals(mapping.getMethod())) {

I would do a patch but I have already modified the DefaultActionMappe for WW-1967 which has
still hopefully outstanding.

Cheers Greg.
