Looks like this was broken by 56a9b02, per @robwormald. Previously
<paper-input>would use theDefaultValueAccessor, now it doesn't get one.A workaround is to implement your own
ControlValueAccessor, probably extending fromDefaultValueAccessor, with a selector that matchespaper-input.One short-term option would be to add an attribute such as
ng-default-controltoDefaultValueAccessor's selector, to allow that directive to be applied to an arbitrary input-like element, at least until #3011 is fixed.alxhub commentedon Nov 2, 2015
Addressed in #5076.
