Bug? B4i Issue: <view>.Visible = True Fails After <view>.SetVisibleAnimated(<duration>, False)

[b4x-de]

I’ve encountered an issue in B4i when changing the visibility of views after using SetVisibleAnimated. When a view (i.e. Panel1) is hidden with Panel1.As(B4XView).SetVisibleAnimated(Duration, False), it cannot be made visible again using the standard Panel1.Visible = True property. Even calling Panel1.Visible = True followed by SetVisibleAnimated(0, True) does not restore visibility. Only a direct call to SetVisibleAnimated(0, True) works. Example scenarios:

Scenario 1 (does not work – panel stays invisible):

Panel1.As(B4XView).SetVisibleAnimated(500, False)
Sleep(600)
Panel1.Visible = True

Scenario 2 (does not work – panel stays invisible):

Panel1.As(B4XView).SetVisibleAnimated(500, False)
Sleep(600)
Panel1.Visible = True
Panel1.As(B4XView).SetVisibleAnimated(0, True)

Scenario 3 (works – panel becomes visible):

Panel1.As(B4XView).SetVisibleAnimated(500, False)
Sleep(600)
Panel1.As(B4XView).SetVisibleAnimated(0, True)

This behavior happens in B4i only; the exact same code works correctly in B4A.

I reported this two years ago and was under the impression that it was solved a long time ago. Do you use the latest version of B4i?

Sanity check: Isn't ".SetVisibleAnimated(0, True)" and ".Visible = True" the same?

Shouldn't these two in effect do the same thing? myPanel.SetVisibleAnimated(0, True) myPanel.Visible = True I have a situation where I used the bottom one, because that worked fine in B4A and B4J. However, in B4i I need to use the top one to make the panel visible. (If it matters, the...

I'm still using B4i Version 8.90 (from May 2025) because I'm currently not able to upgrade to Version 10.00. But Erel fixed it in Jun 2024 already?

Tested with B4i v10, with Panel1 declared as B4XView:

Private Sub Button1_Click
    Panel1.SetVisibleAnimated(1000, False)
    Sleep(1000)
    Panel1.Visible = True
End Sub

Works fine.
