Repeating over a list Polymer broken

Asked By: Anonymous

Update: problem with bleeding edge editor not being compatible with the version of serialization/polymer on pub. Need to install versions from SVN.

Repeating over a list appears to have been broken to me.

https://github.com/sethladd/dart-polymer-dart-examples/blob/master/web/bind_and_repeat_over_list_of_primitives/

This is the simplest example I could find and I get the same error:

Internal error: ‘package:serialization/src/serialization_helpers.dart’: Error: line 212 pos 7: unresolved implicit call to super constructor ‘LinkedHashMap()’
class IdentityMap extends LinkedHashMap {

Probably this update from #dartlang 10 Sep 2013 :-

‘New Dart release with search improvements in Editor, and more.

SDK changes include:

HashMap and LinkedHashmap cannot be extended anymore……’

Looks as though Polymer needs updating for this.
