My App is working in Debug and Release mode.
When I build a standalone package it wil start OK.
When I login I connect to a MySql DB to verify password, it is OK.
I can click on a list of DB records to fill another list with results, but this give me an error.
swiftbutton._base_resize (java line: -1)
