B4J Question Pane bug ??

[rdkartono]

I have 32 panes, that I created using designer.

At program, i want to add labels to each panes.

If I debug it, pressing F8 continuously, my codes can work normally (see "correct process by F8.png) , create expected result (see "correct screen.png")

But if I directly press RUN button on the same program, it will crash, saying can not cast label to pane.
(see "error when running.png").
Running in DEBUG mode, or RELEASE mode still make the same crash.

Attached are 3 pictures as proof.

Anybody knows ?

I use B4J 4.20, and JDK 1.8 64 bit edition, on windows 10 64 edition.
I used B4J alot in my projects already... so I believe this is a bug...

The debugger can in some cases allow incorrect conversions to happen. If it crashes in release mode then there is a problem in your code.

@Erel, I will investigate some more..

In the mean time, from this section for adding a label to a pane, what possibly could be wrong ?

Private Sub create_record_panel (pp As Pane,prefix As String)
    Dim ll As Label
    ll.Initialize("lbl")
    ll.Text = "CH "&prefix.SubString(1)
    pp.AddNode(ll,1dip,1dip,-1,-1)
    Log("panel "&prefix&" added")
End Sub

If you see at "correct process by F8.png", you can see logs "Panel R22 added" ... to.... "Panel R32 added", which is exactly as I wanted.
But if you see at "error when running.png", you can see log that "Panel R01 added" was a proof of succesful that above code was executed once.
Executing the next one, will make "label cannot be casted to pane" error exception.
This is something that i couldn't understand. I know the difference between label and pane.

If I make something like this :

dim xx as label
xx.initialize("")
dim yy as pane = xx

then I understand that "label cannot be casted to pane" exception is happened.

But from my code, I want to add a label to a pane, by "pane.AddNode()" function, so .. definitely not casting label to pane, right ?

Enlightened me please.

It is always better to post the code and the error message as text instead of screenshots. The error is in the For Each xx As Pane In ...
Pane.GetViewsRecursive will return all the views. Apparently there are non-pane views as well.

I uploaded the program. If you have time, kindly check.

See my previous answer.

This line is wrong: For Each xx As Pane In RecordingPane.GetAllViewsRecursive

Not all the child views are Panes so it will throw an exception.
