Envjs envjs

DOMElement.prototype = new DOMNode;
__extend__(DOMElement.prototype, {
    addEventListener:     window.addEventListener,
    removeEventListener:  window.removeEventListener,
    dispatchEvent:        window.dispatchEvent,

is defined before $w (event.js) is included into ext.js, so these functions do not exist.

could either change the ordering, or make wrapper functions instead:

DOMElement.prototype = new DOMNode;
__extend__(DOMElement.prototype, {
    addEventListener:     function(){ window.addEventListener.apply(window, arguments) },
    removeEventListener:  window.removeEventListener,
    dispatchEvent:        window.dispatchEvent,

DOMDocument also has similar pointers, and also to attachEvent/detachEvent
