Hi, I have been stumbling on the following issue when trying to use the File API. My error handler is never called when I call the ReadAsXXX methods on the async API (FileReader, not FileReaderSync) for a file on which I do not have read permissions. Instead an exception in thrown. I have checked the spec and run my test sample with Chromium and I think the current behavior in FF is not correct. I am including a sample for you to assess the validity of my bug report.

Regards

Lukas

The error handler is now called and I get "Error event: undefined".
