Back
you have been provided a working solution..
If you feel the accept attribute does'nt perform the behaviour you expect
you may
1)File a JIRA saying this tag isnt accomplishing the expected behaviour
https://issues.apache.org/struts/secure/Dashboard.jspa
2)Download the Tag source and modify to your requirements
http://svn.apache.org/viewvc/struts/struts2/tags/
Good Luck/
