in md-tabs directive, md-no-bar cause error when md-no-ink is not present

[phil-lgr]

Hello,

I have an issue with the mdTabs directive: this works
<md-tabs md-selected="selectedIndex" md-no-ink md-no-bar >

This doesn't work
<md-tabs md-selected="selectedIndex" md-no-bar >

So it seems that md-no-bar needs md-no-ink..

Plunkr: http://plnkr.co/edit/BKshHA1QZRZSQqJoP13Q?p=preview

Additionally,

Why is not possible to do something like

<md-tabs md-selected="selectedIndex" md-no-ink="disableInk">

and then in the controller, to do $scope.disableInk = true; It seems that the boolean value for md-no-ink or md-no-bar, etc are not passed in the scope.

Best regards,
Phil
