The creation of the StatusController class is missing some steps. This results in the statusbar not displaying when the application is run after following the printed instructions. The downloaded source code is correct. The missing steps are the creation of the line private StatusView statusView; and the creation of the methods @Override public void handleEvent(AppEvent event) { forwardToView(statusView, event); } and @Override public void initialize() { super.initialize(); statusView = new StatusView(this); }

URL string is not enclosed in quotes and line is missing semi-colon - first line of code snippet in step 3. Should be final String TEST_DATA_FILE = "http://feeds.feedburner.com/extblog";

Step 1 reads "...remove all the existing code apparent from the line...". This could be interpreted as "everything after the line...". Based on the sample code, the text should actually read "apart from"
