Chrome apps don't allow unload event handlers

[alxlo]

When using sockjs 0.3.4 as part of a W3C packaged app (Chrome App), sockjs-0.3.4.js:595

utils.attachEvent('unload', unload_triggered);

results in an error message "unload is not available in packaged apps."

Does this actually prevent your app from working? From what I can tell it is just a warning. You can use https://developer.chrome.com/apps/runtime#event-onSuspend and then close the connection manually if you want.

It really is just a warning and everything seems to work as expected.
