[gradebook2-dev] Refreshing the column headers

[Jim Eng]

Thanks, Thomas.  And thanks, Mike.  I think your responses to both issues will give David the info he needs.  And he will follow up with more questions if need be.

Is that correct?  I think David has already written code that puts corrected values in the header cells (corrected to fit the updated context), but they are not showing up. Can you tell us what method call in the event handler would cause the headers to refresh?
