Android Question Click a button on another page

[JOTHA]

Hello community,

I want to click a button on another page (with B4XPages) via code 1 time per minute.

The button is in a class called "Modul_30".
The button is called "L30_SwiftButton_02".
If I click the button with "L30_SwiftButton_02_Click" on this page, everything works.

But when I click this button with "M30.L30_SwiftButton_02_Click" from another page, the following error message is shown:
java.lang.RuntimeException: Class instance was not initialized (modul_30).

Does anyone know how I can click a button on another (non-visible) page from a visible page?

Thank you in advance for your tips and help.

how I can click a button on another (non-visible) page from a visible page?

I have this code in B4XMainPage. P4 is initialized in B4XMainPage. You probaly have to declare P4 as public to access it from other pages other than B4XMainPage

Sub lbl_Click
    B4XPages.MainPage.P4.bxChart_click
End Sub

I have this code in P4:

Private bxChart As Button
Sub BxChart_Click
    Log("hello")
End Sub

If I click on the lbl in B4XMainPage, I get: Hello

declare P4 as public to access it from other pages

Thank you Mahares!
That was the problem (I didn't set it to "Public")
