How to get zk zhtml url parameter?

Question

I'm using Zk framework and trying to get a url parameter from zhtml page. I've tried:

Executions.getCurrent().getParameter("param");

It doesn't work for zhtml although I tried both zscript in the client side and page composer in the server side. But it is working for a zul page. How can I get a url parameter of zhtml as an example:

http://localhost:8080/pystest/reset_password.zhtml?param=xxx

Here is my zhtml page:

<!DOCTYPE html>
<?taglib uri="http://www.zkoss.org/dsp/web/core" prefix="c" ?>
<html lang="en" xmlns:zk="zk" xmlns:z="zul">
<head>
    <meta charset="UTF-8"/>
    <title>Reset Password</title>

    <meta name="description" content="User reset password page" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

    <!-- basic styles -->

    <link href="css/strap.css" rel="stylesheet" />
    <link rel="stylesheet" href="css/font.css" />

    <!-- fonts -->

                                        </div>

                                        <div class="toolbar center">

            ]]>
        </zk:zscript>
</body>
</html>

And server side:

public class ResetPasswordComposer extends GenericForwardComposer<Component> {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    protected Textbox password1;
    protected Textbox password2;

    @Override
    public void doAfterCompose(Component comp) throws Exception {
        super.doAfterCompose(comp);
    }

    public void onClick$resetButton(){
        UserOperator userOperator=new UserOperator();
        try{
            String token=getToken();
            System.out.println(token);
        }catch(Exception e){
            e.printStackTrace();
        }

    }

    private String getToken(){
        Execution exec = Executions.getCurrent();
        String param=exec.getParameter("param");
        return param;
    }
}

In zul, one can access query parameter `foo` with: `${param.foo}` — , Dec 28 '13 at 10:35
I've done it in a different way inside Filter class. By using HttpServletRequest's session parameter i can take the value. — Brucevilla, Dec 28 '13 at 15:47

Your problem is actually that the

private String getToken(){
    Execution exec = Executions.getCurrent();
    String param=exec.getParameter("param");
    return param;
}

Is only available in the doAfterCompose cyclus.

Asked it there and save it as a global string.
