I loaded the code of an app in and changed the text of some buttons to icons(awesome/material).
in debug mode no problem, but in release mode it shows '"Button must be initialized first" error.
I made the attached code that exhibit the same problem.
SOLVED
After a lot of work I decide to wipe out B4A and SDK build-tools r24.4.1 form the computer.
Then reinstall SDK r24.4.1 and reinstall B4A v6.50 Beta #3.
It is working now.
Thanks.
