Hi everyone!

I'm trying to retrieve some data from a database's table in a spinner whose field is of type "enum" with the values 'A', 'I' and I use a list and a foreach iteration inside a Job to do it, but I get an error "Invalid Double"?? it's a string what I'm trying to retrieve from the database and I don't understand what I'm doing wrong. Thank you very much.

Here's my code:
JobDone:
Case  EDITARXREGISTRO
                Dim ListEdicion As List
                ListEdicion.Initialize
                ListEdicion = parser.NextArray
                For i = 0 To ListEdicion.Size - 1
                 
                    Dim MapaListEdit As Map
                                 
                    MapaListEdit = ListEdicion.Get(i)
                    Log(MapaListEdit)
                 
                Next
             
                For Each colroot As Map In ListEdicion
                 
                    Dim clave As String = colroot.Get("ID")
                    Dim nombre As String = colroot.Get("NOMBRE")
                    Dim estado As String = colroot.Get("ESTADO")
                 
                    Log(clave)
                    Log(nombre)
                    Log(estado)
                 
                
                    txtNombre.Text = nombre
                    spEstado.GetItem(estado)
The Map Log:

B4X:
(MyMap) {ID=2, NOMBRE=MARZO-ABRIL, ESTADO=A}
the Error Log:

it expects a double? You are giving a String with the Content A
Hey Don GetItem returns a string Am I wrong? SelectedItem it's read-only and I need modify that value later that's the reason I'm using GetItem but it doesn't work. Thank you for answering

I just need that spinner (spEstado) retrieves the object "estado" ... I mean 'A' or 'I' .

Well.. I've changed my code..

B4X:
txtEstado.Text = estado
spEstado.AddAll(Array As String("A","I"))
