Android Question Problem with a spinner

Hi,
Dim sSectores As Spinner

Activity.Title = "PortIt - Tenencia"
Activity.LoadLayout("posicion") ' Loads "Page1" layout file
'sSectores.Initialize("")
sSectores.Add("Lider")
sSectores.Add("General")
sSectores.Add("Bonos")
sSectores.Add("Opciones")

sSectores is a spinner defined in the posicion.bal

When I run the app the spinner is empty, no options, initialize it or not.
Any Idea?
