Android Question Problem with inputlist, when click freeze

[scsjc]

Sometimes after click on an item of a inputlist it freezes, log:

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.lang.ref.WeakReference.get ()' on a null object reference

Sub cargaservidores
    Dim mylist As List, seleccionado As Int = 0
    mylist.Initialize
    mylist.Clear
    Private cursor1 As Cursor
    Private sql1 As SQL
    sql1.Initialize(File.DirInternal, "user.db", False)
    ime1.Initialize("ime1")
    ime1.HideKeyboard
    cursor1=sql1.ExecQuery(" select host,activo from salas group by host having activo=1 order by host COLLATE NOCASE")
    If cursor1.RowCount> 0 Then
        For i=0 To cursor1.RowCount-1
            cursor1.Position=i
            mylist.Add(cursor1.getstring("host"))
            If cursor1.getstring("host")=server Then seleccionado=i
        Next
        Dim idlist As Int
        idlist = InputList(mylist,"Seleccionar servidor",seleccionado)
        If idlist>=0 Then
            If server<> mylist.Get(idlist) Then
                'si el server seleccionado no es el encurso lo carga...
                server=mylist.Get(idlist) & ":6667"
                log("sub carga server")
            End If
        End If
    End If
    sql1.close
    cursor1.close
End Sub

What is calling cargaservidores?

The solution is to move the code with the InputList to a different sub and call this sub with CallSubDelayed2 (pass mylist as a parameter).
