This issue was originally filed by rob....@gmail.com

I've got a minimal setup at https://github.com/robsyme/dartbug-DataTransferItemList to replicate the error.

What steps will reproduce the problem?

  1. git clone https://github.com/robsyme/dartbug-DataTransferItemList.git
  2. cd dartbug-DataTransferItemList
  3. cd app
  4. dart2js --verbose -o error.dart.js error.dart
  5. Open web error.html in chrome or firefox
  6. Open javascript console.
  7. Drag file into the white box.

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

I expect that the file name of the dragged file printed to the console. Instead, an error is thrown:

Uncaught TypeError: Object #<DataTransferItemList> has no method 'item'

When run in dartium (after the relevant script tags have been changed in error.html), the file path is printed as expected.
The docs at http://api.dartlang.org/docs/releases/latest/dart_html/DataTransferItemList.html#item suggest that there is a method 'item'.
