#9446 closed bug (fixed)

Chained Deferred.pipe functions don't keep the original context from Deferred.resolveWith

Reported by: [email protected] Owned by: jaubourg
Priority: low Milestone: 1.next
Component: deferred Version: 1.6.1

Blocked by: Blocking:


If I chain multiple pipes and use resolveWith like so...

var defer = $.Deferred();
var promise = defer.pipe(function(x) {
    // `this` will be `obj`
    return x * 2;
}).pipe(function(x) {
    // `this` will be `defer`?
    return x - 1;
defer.resolveWith(obj, [5]);

...the first pipe function will get this set to obj as I expect, but the next function in the chain will get its context set back to the Deferred object. I would expect the context to be passed along the chain, so that the second pipe function also gets this set to obj.

Fixes #9446. Context is properly propagated using pipe. If context was the original deferred, then context is updated to next deferred in the chain. Unit tests added.
