iOS Question Object was not initialized

[db0070]

I get this error when I go from Main Page to MyPage to another:-

Error Occured on Line: 0 (MyPage)
Object was not initialized (UILabel)

Yet, when I put a break point after the Show call, there is no error. What could be wrong?

Is this the full error message?

The problem happens in LocManager_AuthorizationStatusChanged. You are setting the visibility of a label before it was initialized.

Add a check with If SomeLabel.IsInitialized Then ...

I added to all labels 'If xxxx.IsInitialized then ...' still I get the same error. I don't understand, because when the layout is loaded that should initiliaze all views. I do not add any view by code. And why it works when I put a break point on the last line at End Sub and then continue run?

Public Sub ShowSalat
    If pg2.IsInitialized = False Then
        pg2.Initialize("pg2")
        pg2.Title = "Salat Times"
        pg2.Initialize("pg2")
        pg2.RootPanel.LoadLayout("salatcalc")
    End If
    Main.Page1_Resize(Main.ActivityWidth,Main.ActivityHeight)           

    Main.navControl.ShowPage(pg2)
    ActivityCreate
End Sub

Can you post more code? Or the full project?

I had the same problem. I fixed it by adding

pg2.RootPanel.LoadLayout("pg2")

before

NavControl.ShowPage(pg2)


Hope this helps
