ng-repeat in %angular

[Jeff Steinmetz]

Any thoughts on why the example below only displays the first item in the list, 
“lisa”, followed by an empty object, then stops?
or specifically:

lisa
{}


The two notebook paragraphs (first %spark, then %angular) are:

%spark

val friends = List("lisa","jeff","mary","sun")
z.angularBind("friends", friends)


%angular

<div ng-repeat="f in friends">
  <div>{{f}}</div>
</div>
