Facing Error "duplicate declaration of ‘Screen2’" after copy screen

Don’t know how you did when copying the screen but you had a Vertical Arrangement named as Screen2 on Screen2 and thereby error, renamed it to something else and it works now

Custom_ListView_Demo1.aia (1.8 MB)

A thought though, you named your Arrangement to Screen2 on Screen1, copied Screen1 to Screen2 and you got the end result with two identical names

You should start introducing this naming to your components
