B4J Question [ABMaterial] Button_clicked work first time

[hibrid0]

Hi guys, I'm just playing wit

h ABMaterial and is too amazing.
Just create webapps just writing on basic.

But I have an small problem. On the first excution if I make click on the button, work fine, but I make some process (I use the FileDownload example), after upload the file to the server, the button link not goes.

I see the file upload fine.
I see if the others functions work fine. and is ok.
If a wait some seconds the app crash and show the Log Clicked, on the log wall.

Sub Class_Globals
        Dim btndownload As ABMButton

end sub

Sub ConnectPage()
    btndownload.InitializeRaised(page, "btndownload", "mdi-file-cloud-download",ABM.ICONALIGN_LEFT, "Testing Button", "myTheme")
    btndownload.Enabled=False
    btndownload.Refresh
    page.Cell(6,1).AddComponent(btndownload)

End sub

Sub btndownload_clicked(Target As String)
ABMShared.NavigateToPage(ws, ".\")
Log("Test button Clicked")

  
End Sub

Yes, using delays may interfer with the connection to the websocket. Avoid them as much as possible.
