nit: It feels a bit awkward that this top-level function is calling what looks
like a private function (viz "_"). Should the function be called updateControls

Yeah, I think you're right. I will make updateControls "public".
Done.

maybe the original idea here was, that this property will be 'unset' in the else
case.

[stevenjb, 2014/09/08 23:25:16]

I thought of that, but I don't see any advantage to that behavior.
'Cellular.APN' is only ever relevant if 'Cellular.APNList' is non empty.

Eventually 'onc_' needs to be read-only so that the UI reflects whatever the
values actually get set to after and update gets sent.

not sure whether that has the intended effect:

if showBuyButton _was_ true
and changes to not existent, then you will not hide the element anymore.

same for below.

[stevenjb, 2014/09/08 19:43:12]

Ugh. So, this variable isn't even used, I'll remove it, but the logic for the
others is not what one would expect - not present does in fact mean 'false'.
Since we want to remove that logic from the C++ code anyway, I'm not going to
fix that, I'll just restore the JS logic.

[pneubeck (no reviews), 2014/09/08 09:18:00]

this seems to have been unreliable already in the old code?
i.e. if 'details-internet-login' was already hidden and should now be visible,
it will not appear.

IIUC, this seems to be a common problem in this function: there are several
guarded assignments to 'hidden'...

[stevenjb, 2014/09/08 19:43:12]

Yeah, I fixed this one here and in showDetailedInfo.

[stevenjb, 2014/09/08 21:31:18]

Actually, it turns out this overrides 'details-internet-login.hidden' set in
updateConnectionButtonVisibilty_() iff showActivateButton is true, so the
original logic was correct.
