Hello,
after a while working on already existing app designer code I got a weird error when starting the app GUI.
Error using feval.
Error defining property 'Machine' of class 'TemperaturGUI':
Class named 'MachineManager' is undefined or does not support property validation.
I could solve the problem by copying the missing files out of its own folder in my GUI folder. But now there are way too many files in my GUI folder and I would like that the app can use the files from their own folders which are in the same main folder like the GUI Folder (just like it had been before).
I already tried using addpath in the Startup function of the app but it still wont recognize the files.
