| - | For example: if you want to load all the measures of a document, it's easy to think that the ''LoadAll()'' method would be available in the ''FCMeasures'' class. However, it's not. Instead, it's implemented in the ''_FCCollectionData'' parent class and that method will affect many other child classes, such as ''FCPages'', ''FCStaffSystems'', etc. | + | For example: if you want to load all the measures of a document, it's easy to think that the ''LoadAll()'' method would be available in the ''[[http://www.finaletips.nu/frameworkref/class_f_c_measure.html|FCMeasures]]'' class.

| * The currently used conversion layer between Lua and C++ doesn't support optional arguments in method calls (this might change in the future, though). So in Lua, you need to provide all the arguments to a PDK Framework method. | * The currently used conversion layer between Lua and C++ doesn't support optional arguments in method calls (this might change in the future, though).
