how can you extract mutiple values from catch?

[emaayan]

hi..
according to cockpit promises, the catch portion may return an additional parameter

from what i understand you can't have more then one value on a callback in promise

In case it's still relevant: you can access extra arguments by calling Js.arguments(). Alternatively you can define your own class for the promise, similar to elemental2.promise.Promise, but change CatchOnRejectedCallbackFn to accept multiple arguments (since this is a difference between standard Promise and Cockpit API, it should not be part of Elemental).
