Exact, an element removed may be add it elsewhere and my purpose is out ....
It remains that the proposal of Mike element.descendants (). invoke ( 'stopObserving'); element.stopObserving (); But I find it rather heavy for the developer who must insert code to delete each element and can also cause performance's problems. Could not we consider making public the method _destroyCache and add it an optional parameter "ancestor"? Expl : function destroyCache(ancestor) { ancestor = $(ancestor); for (var i = 0, length = CACHE.length; i < length; i++) { if (!ancestor) || (CACHE[i].descendantOf // Possible on Window / Document Elements && (CACHE[i].descendantOf(ancestor) || CACHE[i].match(ancestor))) { Event.stopObserving(CACHE[i]); CACHE[i] = undefined; } } CACHE = CACHE.reject(Object.isUndefined); } This method could be integrated also at the AjaxUpdater before replacing the content ?
