Hi Erel, all.
I have 2 Activity B4XPages and this code.
B4XMainPage:

B4X:
'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
    'load the layout to Root
    Root.LoadLayout("lay_main")
    Page2.Initialize
    'B4XPages.AddPage("Page2", Page2)
    B4XPages.AddPageAndCreate("Page2", Page2)
    'Page2 = B4XPages.GetPage("Page2")
 
End Sub

Sub B4XPage_Appear
    Log("sono qui")
    WobbleMenu1.SetCurrentTab(1)
End Sub

'You can see the list of page related events in the B4XPagesManager object. The event name is B4XPage.

Sub WobbleMenu1_Tab2Click
    'B4XPages.ShowPageAndRemovePreviousPages("Page2")
    B4XPages.ShowPage("Page2")
End Sub

B4XPage2:

B4X:
'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("lay_page2")
 
End Sub


Sub WobbleMenu1_Tab1Click
    'B4XPages.ShowPageAndRemovePreviousPages("MainPage")
    B4XPages.ShowPage("MainPage")
End Sub

Sub B4XPage_Appear
    Log("Appear Page2")
    WobbleMenu1.SetCurrentTab(2)
End Sub

Sub B4XPage_Disappear
    Log("Disappear Page2")
End Sub

in MainPage i have
B4X:
B4XPages.AddPageAndCreate("Page2", Page2)
So the page2 already create in this step and after we "play" only with B4XPages.ShowPage, but still i get the unwanted effect of the refresh
Anyway when i click in
B4X:
Sub WobbleMenu1_Tab2Click
    B4XPages.ShowPage("Page2")
End Sub
i have this "refresh" , where and how if the activity was recharged.
I also tried to eliminate Animation Duration = 0 in Design but dont change nothying.

Where i wrong ? Is it possible to have a "linear" effect (as at the end of the movie) without having the refresh.

Thank you
Marco
