Add debug information to verify that we actually get the onDone event send to the driver page.

Rename to 'Sending events to driver page.'

(why did you call it 'onDone'?)

[ricow1, 2013/11/29 08:21:52]

So this should have been isDone, I only do this if we have the isDone bool set

[kustermann, 2013/11/29 08:26:23]

Sorry about that, please remove the 'if (isDone) {}'. 
I think it would be beneficial if we get this info every time we contact the
driving page (be it a status update or the final update)

So do something like this:

recordEvent('debug', 'Sending events to driver page (isFirstMessage = ' +
isFirstMessage + ', isStatusUpdate = ' + isStatusUpdate + ', isDone = ' + isDone
+ ')');

unconditionally

+    }
     // Post the DOM and all events that happened.
     var events = recordedEventList.slice(0);
     events.push(buildDomEvent());
 
     var message = JSON.stringify(events);
     driver.postMessage(
         JSON.stringify({
           message: message,
           is_first_message: isFirstMessage,
           is_status_update: isStatusUpdate,
