I have a problem using structures in the App Designer properties. I'm new on App Designer and I would like to have some common variables to all the callback functions. In the original script that I'm using, these variables where ordinated in a structure but I'm not able to do the same in the App Designer. The error it is relative to the use of the dot when I write a structure array.
How can I solve this problem and to continue using structures also in App Designer?
