catching error - async Promises

[mbana]

Hi,
I see the errors are caught in particular Polymer functions only.
Is there a way to catch errors, that occur in the then function of a Promise created in your component?
The only thing i can think of at the moment is doing another wrap using Polymer.Base.Async in one of the then functions of the Promise.

This isn't ideal, so I was wondering if there is a better way of doing this.
