how to remove mask from field

[Ben Erridge]

I am using icefaces and the input mask sometimes the script that creates an input mask runs twice. I want to remove any previous input masks on a given element.
what is the best way to accomplish this?
Thanks

I have been successfull removing eventlisteners from firefox and chrome but ie I still can't get to work correctly.
I added a new function to JavaScriptUtils.js

    function removeObserver(object,eventName,handler){
        object=getObject(object);
        if(object!=null){
            if(object.removeEventListener){
                object.removeEventListener(eventName,handler,false);
            } else if(object.detachEvent){
                object.detachEvent("on"+eventName,function(){
                    return invokeAsMethod(object,handler,)
                })
            } else {
                object=null;
            }
        }
    }

as well as adding function to InputMask.js

    this.disable=function(){
            removeObserver(this.control,"blur",onBlur);
            removeObserver(this.control,"focus",onFocus);
            removeObserver(this.control,"keyup",onKeyUp);
            removeObserver(this.control,"keypress",onKeyPress);
            removeObserver(this.control,"keydown",onKeyDown); 
        }

No luck with IE though any help would be greatly appreciated!

It's possible that event names in IE are case-sensitive. Therefore onblur <> onBlur. Check this out.

Another option is to look at the YUI library, it has a good support of event listeners, perhaps you can copy some code snippet from there.
