Android Question B4XTable selections: crash

[toby]

I'm getting errors while trying to implement table row selection. Could someone let me know what's wrong, please?

Steps to reproduce:
1. set one or more column to be hidden, such as

    B4XTable1.VisibleColumns.RemoveAt(B4XTable1.VisibleColumns.IndexOf(NumberColumn))

2. Implement table selections as instructed here

You should get error logs like the following

My workaround is to modify B4XTableSelections.Refresh() code

        Dim j As Int =mTable.VisibleColumns.IndexOf(col)
            If j>=0 Then
            Dim p As B4XView = col.CellsLayouts.Get(i + 1)
            Dim lbl As B4XView = p.GetView(col.LabelIndex)
            If RowSelected And (LineMode Or SelectedCells.IndexOf(col.Id) > -1) Then
                p.Color = SelectionColor
                lbl.TextColor = SelectedTextColor
            Else
                p.Color = clr
                lbl.TextColor = mTable.TextColor
            End If
            End If
