Lesson Builder - Missing Warning (Gradebook)
While testing Lesson Builder in rc03 on  I found a problem with the instructor view for grading LB pages without a gradebook in the site using IE9 & FF16.
If an instructor attempts to change the settings on a page such that it is graded, the following warning is supposed to be displayed:
This item couldn't be marked for grading. The most likely issue is that no Gradebook tool has been added to this site yet.
However, on  there are no warnings displayed at all and the gradebook settings are saved.
