struts ignores the method and shows no exception

Question

I have a struts method and it was working fine before i added the validation, but once i added the validation method the method which i call is not called and it shows no exception also.

struts-config.xml

<action path="/RolesAction"  name="SecurEyesForm" type="com.secureyes.eswastha.struts.web.action.RolesAction" scope="request" parameter="method" validate="true" input="/WEB-INF/Masters/RolesMaster.jsp">
  <forward name="rolesHome" path="/WEB-INF/Masters/RolesMaster.jsp"></forward>        
</action>

action class :

    }
}

and this is how i call the method :

function dataSave() {
                alert("data Save");
                getBlanket('continueDIV');
                document.forms[0].action="RolesAction.htm";
                document.forms[0].method.value="saveRolesDetails";
                document.forms[0].submit();   
            }
