can anybody help me with dynamic param in menu-config

Hi All,
        presently we are using struts-menu in our project. It is working
fine till now but we want to add dynamic value to query string
example
line from menu-config file

 <Item   name="PCHVisitList"   title="
patientcasehistorymenu.label.patientvisitlist" image="images/party-new.png"
                    
action="PatientCaseHistoryAction.do?method=PatientVisitList&amp;patientId=${patientId}"
width="100" />

when I click on respective menu item Iam getting patientId=${patientId}
displayed as it is in the browser, instead of patientid=345(which i set in
action class to session attribute)

It would be of great help if any body can show me working example or help me
fix this.

Iam not using any velocity here. Do I need to use that???
