B4J Question b4j and b4xbitmap

[LordZenzo]

I have this problem
in main

Sub AppStart (Form1 As Form, Args () As String)
MainForm = Form1
MainForm.RootPane.LoadLayout ("first") 'Load the layout file.
MainForm.Show
DialogXUI2.LoadBmpOkButton (xui.LoadBitmapResize (File.DirAssets, "Done600.png" 100dip, 100dip, True))
End Sub

in CustomView (dialogXUI)

public Sub LoadBmpOkButton (bmp As B4XBitmap)
OkButton.SetBitmap (bmp)
End Sub

when it assigns OkButton which is a b4xView (bread) it creates this error for me

Waiting for debugger to connect...
Program started.

why this ?
java.lang.ClassCastException: anywheresoftware.b4j.objects.PaneWrapper $ ConcretePaneWrapper $ NonResizePane cannot be cast to javafx.scene.image.ImageView
why if I only use b4xbitmap, does it tell me this?

Always pay attention to the B4XView methods documentation. It tells you which views support each method. SetBitmap is only supported by ImageView in B4J and B4i. Add an ImageView to the panel.

yes, after several tests I understood this
that I can't use B4xView directly but ImageView-> b4xview to use the setbitmap method
