iOS Question [SOLVED] This class is not key value coding-compliant

[Emme Developer]

Hi all, i've different checkbox (class) inside a panel. Since i add them by code, i put them in a global list to avoid iOS release instance (i use tag for other things)
When i try this simple code, i get different error. In Simulator all works without issue, but on iphone 6s i have some problems

CODE

If prog Then Return
        Dim v() As Object = Tag_
        Dim send As CheckBox = Sender

        If checked Then
            SelectedList.Add(send.Tag)
            SelectedText.Add(send.Text)
        Else
            SelectedList.RemoveAt(SelectedList.IndexOf(send.Tag))
            SelectedText.RemoveAt(SelectedText.IndexOf(send.Text))
        End If
  
        If Not(SelectedList.Size < v(0)) Then
            For Each vv As CheckBox In ListTemp
                If Not(vv.Checked) Then vv.Enabled = False
            Next
        Else
            For Each vv As CheckBox In ListTemp
                vv.Enabled = False
            Next
        End If

Spoiler: Error

This happens if i put code inside a try catch

This happens without try/catch

Thanks @Erel, with your code i see that i added also a button into the list. But i don't understand why in simulator works, and on real device no. By the way, i solved the issue
