B4J Question Help me to solve an error with open an B4XPages

[universengo]

Hello Pro!
I have a project B4xPages with 2 layouts and I have an error when opening an other layout.

B4XPage 1:

Private Sub OpenPage2_Click
    Page2.Initialize
    B4XPages.AddPage("Page2", Page2)
    B4XPages.ShowPage("Page2")
End Sub

B4XPage 2:
Public Sub Initialize As Object
    Return Me
End Sub

'This event will be called once before the page becomes visible.
Private Sub B4XPage_Created(Root1 As B4XView)
    Root = Root1
    'load the layout to Root
    Root.LoadLayout("Page2")
End Sub

When I open Page 2 that shows me an Error as below (Although before the time I opened normally ):

The code looks like that it is ok, could you post a small project?

It would be easier to help you if you posted your project as a zip file.

Something wrong in your code using B4XTable.

Thanks all, I fixed this error (because I changed B4XTable to TableView on the frmPage2 form but I couldn't change Delare for it (example: Private Tbv1 as B4XTable -> Private Tbv1 as TableView (OK))
