I get the Event.unloadCache but let's say you have something like this:
<div id="test">
</div>
script is:
Event.observe('test', 'click', function(){ alert('I am so happy') })
Your Event.observers.length is 1
then you want to remove test, so before you actually remove it from the
dom you are kind enough to say,
"hey, test div, stop observing that click and go have a beer"
Event.stopObserving('test', 'click', function(){ alert('I am so happy')
})
You would think that observer would have beer and get out of the
Event.observers array so length would equal Zero.
But it doesn't, so I complain. So now the Event.unloadCache() cycles
through observer objecst that don't exist anymore which doesn't seem
right.
Also, I don't think that hard to fix just put after line
element.removeEventListener(name, observer, useCapture);
this.observers.pop([element, name, observer, useCapture]);
and
element.detachEvent('on' + name, observer);
this.observers.pop([element, name, observer, useCapture]);
Just my 2 cents.
