Creating a disableable AjaxSubmitLink

[Anthony J Webster]

Hi,

I'm trying to create a disableable AjaxSubmitLink. When a user clicks on the 
link further clicks must not result in anything until the 'submission' is 
complete. This call be achieved by adding "return false;" in a call decorator. 
However I'm stuggling with the re-enabling. I need to strip the "return false" 
and put the original destination back.

form.add(new AjaxSubmitLink("randomise", form) {

            protected void onSubmit(AjaxRequestTarget target, Form form) {
               somethingLong();
            }
            protected IAjaxCallDecorator getAjaxCallDecorator() {
                return new AjaxCallDecorator() {
                    
                    public CharSequence decorateScript(CharSequence script) {
                        return "return false;" + script;
                    }
                    public CharSequence decorateOnSuccessScript(CharSequence 
script) {
                        // NEED TO RESET TO PREVIOUS STATE
                    }
                    public CharSequence decorateOnFailureScript(CharSequence 
script) {
                        // NEED TO RESET TO PREVIOUS STATE
                    }
                };
            }
        });

Any help would be most appreciated.

Thanks in advance

Anthony
