Failing tests:

Course Overview.should save model when save is clicked 77 ms 1
Course Overview.should show a confirmation on save 31 ms 1

Forgot to remove @xhr, which is undefined. Tests should be passing now.

Do you want to keep the hellip; inside the localizable string? This might be confusing to translators? Maybe a string concatenation would be preferable?

[cahrens]

I agree it might be confusing. We've done it in numerous places though. If Peter changes this one, he should change them all.

Perhaps "Saving" should store some common text options (or use Saving.... as the default value).

[peter-fogg]

Since we're changing the Saving type to Mini, I'm not sure if it would make sense to use "Saving..." as the default value. I'll take the ellipsis out of the gettext call; it only occurs in two places.
