I'm rigid thinking that no web page really _requires_ JavaScript, not at
least because some clients using my application will not allow active
scripting in their browser. Sites like e. g. (view with
disabled JS) make me feel confirmed.

Isn't it possible to iterate the request parameters if there's one that
has ".x" and ".y" suffix? Since no one really wants to submit values
with a name like this I suggest the struts framework automatically
generates a parameter so the handling in the action is consistent as for
a submit button. Of course there has to be some tag defining the name of
the "action" parameter.

Wouldn't that be nice?

This method work for me:

    String getActionParameter(Map p_Keys)
        String l_Key;
        Iterator l_iKeys = p_Keys.keySet().iterator();

        while (l_iKeys.hasNext())
            l_Key = (String);
            if( l_Key.endsWith(".x") 
             && p_Keys.containsKey(l_Key.substring(0, l_Key.length()-1)
+ "y"))
                return l_Key;
        return null;

To be used in the execute method of the action:

    String l_Action = getActionParameter(p_Request.getParameterMap());

Thanks for help
