[Rails-spinoffs] Re: prototype: calling onFailure within onSuccess

[Colin Mollenhour]

There appears to be no reference back to Prototype's Ajax object, and even setting new properties in the XHR object is forbidden in IE as Tobie (I think) discovered when we tried to add a responseJSON property. There is a patch for wrapping the XHR object, which could contain a reference back to the Ajax object, but I don't know if it already does or what the status is on that. For now you'll have to declare the function elsewhere and reference it with a closure like Michael suggested or hack the Prototype source to pass an extra argument, but I strongly recommend against that.
