Are there any warnings in the warnings list above the logs?

For example:

[Erel]

See the second one.

I synced the files and tuttoora okay but I still do not know how these errors solve.

the buttons were defined on java fx, and then created with this code, because it gives me error initialize some object ???

Sub Process_Globals

    Private fx As JFX
    Private MainForm As Form
    Private FileSelect As String
 
    Private bt1, bt2, bt3, bt4, bt5, bt6 As Button
    Private lb1 As Label
    Private lw As ListView
    Private tx1 As TextArea
    Private et1,et2 As TextField
    Private sl1 As Slider

End Sub

mistero o errore - mystery or error

 

[Erel]

There is a reason for these warnings. You need to fix them. It is hard to say without seeing the code.

if you need the complete project tell me where I have to send

 

[Erel]

Maybe you haven't saved the updated layout. If you are unable to find the cause of this issue then please upload it here (File - Export as zip).

 

[ivanomonti]

saved with the layout name from javafx, but the problem remains

 

[Erel]

I don't see any button with bt1 id:

 

[ivanomonti]

MMMMMMMM

Mistery .... :-(

 

[Erel]

Not really. Open the fxml file with Notepad++:

You can see that you have set the wrong id on some of the buttons.
