canncellable with isCanncelled()

[samsam007]

Hi,

There are 3 buttons on the jsp web page, first one is submit (sign
in), another one is Cancel, the third one is something else. I used
<html:cancel> for the Cancel and something else.
I also included this.isCancelled() conditional check in the execute()
method; as well as included canecellable="true" in the <action path>
in the struts-config.xml file.
But I don't know why the this.isCancelled() method doesn't returned
true in the execute() method.

Here is the code:

 # cat struts-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD
Struts Configuration 1.3//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_3.dtd">
....
        <action-mappings>
                <action path="/onlinepayment_portlet/sign_in"
type="com.ip6networks.onlinepayment.portlet.SignInAction"
name="SignInForm" scope="session" validate="true" cancellable="true"
input="/portlet/onlinepayment_portlet/sign_in.jsp">
                        <forward name="sign_in"
path="/portlet/onlinepayment_portlet/sign_in.jsp"></forward>
                        <forward name="personal_details"
path="/portlet/onlinepayment_portlet/personal_details.jsp"></forward>
                        <exception key="errors.cancel"
type="org.apache.struts.action.InvalidCancelException"
path="/portlet/onlinepayment_portlet/fool.jsp"></exception>
                </action>
...

SignInAction.java:
....
        public ActionForward execute(
                        ActionMapping mapping, ActionForm form,
HttpServletRequest req,
                        HttpServletResponse res)
                throws Exception {

                SignInForm signinForm = (SignInForm) form;
               req.getSession().setAttribute("SignInForm", signinForm);
                PersonalDetailForm personalDetailForm = new
PersonalDetailForm();
               req.getSession().setAttribute("PersonalDetailForm",
personalDetailForm);

                String email_address = signinForm.getEmailAddress().trim();
                String password = signinForm.getPassword().trim();
if ( this.isCancelled( req ) )
{
System.out.println( "About to forward the cancel!" );
return mapping.findForward( "formTest.cancel" );
}
..

sign_in.jsp:
...
<html:submit property="sign_in">
        <bean:message key="button.sign_in" />
</html:submit>

<html:cancel property="new_visitor">
        <bean:message key="button.new_visitor" />
</html:cancel>

<html:cancel property="cancel_checkout">
        <bean:message key="button.cancel_checkout" />
</html:cancel>

Your help is much appreciated.
Thanks
Sam

Why do you have two cancel buttons?
