What steps will reproduce the problem?

1. Load the project attached as a .zip (also available as this GitHub gist: https://gist.github.com/chalin/9645690)
2. pub build
3. Run under Chrome.
4. Click on the links to see what is returned by calls to the three InputElement.value* properties.
       In particular, notice that reading valueAsDate results in a NullError.

What is the expected output? What do you see instead?

Expected output (as generated from Dartium)
number.value => ''
number.valueAsNumber => NaN
number.valueAsDate => null
date.value => ''
date.valueAsNumber => NaN
date.valueAsDate => null

etc for time, datetime, month and week as well.

Instead, what we get when runing the JS version from Chrome:

number.value => ''
number.valueAsNumber => NaN
number.valueAsDate => Exception: NullError: Cannot call "getTime" on null
date.value => ''
date.valueAsNumber => NaN
date.valueAsDate => Exception: NullError: Cannot call "getTime" on null

etc for time, datetime, month and week as well.

What version of the product are you using? On what operating system?

Dart SDK version 1.3.0-dev.4.1
MacOS X 10.9
