In the calls order "deferred.then(...).fail(...)" the fail callback doesn't receive arguments

[GolubevS79@…]

In the calls chain "deferred.then(...).fail(...)" the fail callback doesn't receive arguments, but the chain "deferred.fail(...).then(...)" works correct.

The same with "done" and "progress" methods.

The .then() creates a *new* promise, I suspect that is what you are trying to describe but there wasn't a test case. This is documented, ​http://api.jquery.com/deferred.then/ so please followup questions to a forum.
