[JW Lua] Calculating the last measure on a page

[Jari Williamsson]

Jan,

Insert a
"finale.FCStaffSystems.UpdateFullLayout()"
call before loading the info.

In general when dealing with page layout, when the user has AUL turned 
ON (which I believe 99% of the users have nowadays), the layout info 
related to systems and measures must be updated before reading. However, 
also make sure to not make unnecessary calls to 
finale.FCStaffSystems.UpdateFullLayout(), since it's very time expensive.


Best regards,

Jari Williamsson
