onSuccess executed only if onComplete checks succeeds ..

[imbibinebe]

Hi there
I develop a mobile app with a
controller > view architecture combined with asynchronous AJAX requests.
In order to avoid memory leaks, in destroy current controller and view (DOM) when the user switch back to a previous view ([back] button ...)
My onSuccess method uses to update the view depending on data retrieved from the AJAX call and that's why I don't want it to be executed if the user left this view cause it's not surprisingly generating javascript errors ...
tests I have to do are always the same and that's why i didn't want to put them in each of my onSuccess methods (many) since I have an onComplete method which is common to all my requests.
Then here is what I do:

onComplete: function(e)
{
         if(my tests are not OK) {
                this.removeEvents().setOptions({timeout:0}).cancel();
                return;
         }
         ...
         few other things if tests are OK
         ...
}

This is working correctly (onSuccess method is not executed) if the user switch back fast enough on the previous view ([back] button) but not if he waits to long (like 0.5 or 1s more).
Here is what is see in mootools-core source code.

onSuccess: function(){
        this.fireEvent('complete', arguments).fireEvent('success', arguments).callChain();
    },

I thought that onSuccess method were executed only when onComplete method has finished. Isn't it the case ?
Do you have an idea of how I should do ?

these are internal handlers

I would probably prefer to have the this.fireEvent('complete')
independent, preceding this line:
