notifyWith isn't working with $.when

[nticompass@…]

I noticed that when doing

$.when(a(),b()).progress(function(){
    console.log(this);
});

that "this" is always the promise object, even when using ".notifyWith".

Here is an example of this issue: ​http://jsfiddle.net/NTICompass/3DDSa/17/

Modifying line 1336 to use this in place of promise makes the fiddle run correctly, though I don't know what other impacts that may have.

Using when, you "join" two promises. As of 1.8, you also "join" contexts. So, this in the context of your when call is an array containing both contexts. Just deference to get the one context you need: ​http://jsfiddle.net/3D4wq/

So, in 1.7.2, there's no way to get the context from "notifyWhen" when using "when"?

[jaubourg]

Prior to 1.8, the context was always the new promise if one was created (using when with a single promise is a special case that returns the promise as given thus preserving callback contexts). So, yes, you'd have to use 1.8 to have access to the array of contexts.

In general, I find context handling a bit of a pain and tend to favor variables in closures whenever possible.

Replying to jaubourg:

Agreed, I was just messing around, when I noticed "hey, why can't I do this?"
