[JW Lua] Calculating the last measure on a page

[Jan Angermüller]

Jari,

inserting the finale.FCStaffSystems.UpdateFullLayout()
or calling "Update Layout" manually didn't make a change.
Although I know of other cases where the UpdateFullLayout
function call helped me some months ago.

I had to delete the empty pages with page:DeleteData()
or manually.
It seems to me that it was a Finale issue with weird
empty pages. I also have no idea why Finale added
these three empty pages.
