I'm not proud of this hack, but it works.

[Jennifer Messerly, 2013/10/25 22:00:41]

hmmm. interesting I thought PolymerExpressions "Method" workaround should handle
this. but not sure what is going on :)

[Siggi Cherem (dart-lang), 2013/10/26 00:02:35]

me neither. I'll be submitting this shortly and look more into this afterwards.
