Android Question Error occurred on line: 15 (B4XPages)

[Enoch Taylor]

I'm trying to pass a list value from my app Main to B4XMainpage

On my Main I have this

CallSub2(B4XPages.mainpage, "select_clients", list2)

And on B4XMainpage I have this code

public Sub select_clients (title As List)
    'Autocomplete Box
    select_business_name.Setitems (title)
End Sub

But when I start my application I end up getting

java.lang.ClassCastException: java.lang.
Object cannot be cast to b4a.poslitemini.b4xpagesmanager
(Truncated)

When I remove the code line from application Main ==> CallSub2(B4XPages.mainpage, "select_clients", list2), everything works

What are my doing wrong. Thank you

1. Why are you putting code in the Main module?
2. Post the full error message from the logs.
3. Why are you using CallSub2???

B4XPages.MainPage.Select_Clients(list2)

I want to get a list of clients from a database and feed it to an autocomplete control on the login screen.
The login screen is the root.layout of B4XMainpage

I'm using CallSub2 because that is what has worked for me in the past passing values between two classes
I got the idea from here

Passing Data back to calling class..

Need some help on passing data back and forth between open forms on two different classes. I have a class that I call from the Main… when I call the class I call a sub that opens a form. On the form I have a button that calls another class that opens a form so I can select a company from a data...

The app begins with a splash screen which I got codes from here

[B4X] [B4XPages] Splash Screen

B4A, B4i and B4J splash screen implementation. The implementation is different in each platform. 1. Don't miss the manifest editor code in B4A. 2. Don't use %y in the code. Use Root.Height instead (you can use %y in the designer script).

1. You shouldn't put any code in the Main module.
2. You don't need to use CallSub. Call the sub directly.
