Why isn't this handled as a "Result"?

[jrummell, 2014/09/11 21:21:55]

On the Chromium side we switch to CdmPromise, so these are simply the functions
that are called when the promise is resolved/rejected. Renaming the methods
below.

On...?
ditto below

Done.

Why does the CDM object handle a session error?

This is the promise rejected. Renamed.
