Hi Evryone,
I don't why when I compile in debug mode all goes ok, but when I compile in release mode I get this error
B4X:
B4J Versione: 7.31
Java Versione: 8
Analisi del Codice.    (0.06s)
Building folders structure.    (0.02s)
Compilazione del codice.    Error
Errore nella compilazione del programma.
Descrizione dell'errore: ',' atteso.
Errore nella linea: 61
initialize(rdclink)
Word
The source code involved is this class:
B4X:
Sub Class_Globals
    Private rdclink As String
    Private fx As JFX
    Dim id As  String = Null
    Dim nome As   String = ""
    Dim ubicazione As   String = ""
    Dim t_uuid As   String = ""
End Sub


Public Sub setId(vid As String)
    id = vid
End Sub
Public Sub setNome(vnome As  String)
    nome = vnome
End Sub
Public Sub setUbicazione(vubicazione As  String)
    ubicazione = vubicazione
End Sub
Public Sub setT_uuid(vt_uuid As  String)
    t_uuid = vt_uuid
End Sub
public Sub loadByResultset(res As DBResult)
    For Each Row() As Object In res.Rows
 
        id =  Row(res.Columns.Get("id"))
        nome =  Row(res.Columns.Get("nome"))
        ubicazione =  Row(res.Columns.Get("ubicazione"))
        t_uuid =  Row(res.Columns.Get("t_uuid"))
    Next
End Sub
public Sub initialize(rdcUri As String)
    rdclink = rdcUri
 
    id = Null
    nome = ""
    ubicazione = ""
    t_uuid = ""
End Sub

Public Sub getId As String
    Return id
End Sub
Public Sub getNome As  String
    Return nome
End Sub
Public Sub getUbicazione As  String
    Return ubicazione
End Sub
Public Sub getT_uuid As  String
    Return t_uuid
End Sub

Public Sub getPostazioniById(vId As Object) As ResumableSub
    Dim res As DBResult = Null
    jRDC2Utils.Intitialize(rdclink)
    Wait For (jRDC2Utils.ExecuteQuery(jRDC2Utils.CreateCommand("select_postazioni_byId", Array(vId)))) complete (res As DBResult)
    If Not(res = Null) Then
        loadByResultset(res)
    Else
        initialize(rdclink) ' ******** THIS IS THE LINE 61 OF THE COMPILE ERROR
    End If
End Sub
Public Sub getListaPostazioni() As ResumableSub
    Dim res As DBResult = Null
    jRDC2Utils.Intitialize(rdclink)
    Wait For (jRDC2Utils.ExecuteQuery(jRDC2Utils.CreateCommand("select_lista_postazioni", Array()))) complete (res As DBResult)
    If Not(res = Null) Then
        Return res
    Else
        Return res
    End If
End Sub
public Sub delete() As ResumableSub
    jRDC2Utils.Intitialize(rdclink)
    Wait For (jRDC2Utils.ExecuteCommands(Array (jRDC2Utils.CreateCommand("delete_postazioni", Array(id))))) complete (count As Int)
End Sub
Public Sub insert() As ResumableSub
    jRDC2Utils.Intitialize(rdclink)
    t_uuid = jRDC2Utils.generateUUID()
    Wait For (jRDC2Utils.ExecuteCommands(Array (jRDC2Utils.CreateCommand("insert_postazioni", Array(nome,ubicazione,t_uuid))))) complete (count As Int)
End Sub
Public Sub update() As ResumableSub
    jRDC2Utils.Intitialize(rdclink)
    Wait For (jRDC2Utils.ExecuteCommands(Array (jRDC2Utils.CreateCommand("update_postazioni", Array(nome,ubicazione,t_uuid,id))))) complete (count As Int)
End Sub
private Sub retriveID() As ResumableSub
    Dim res As DBResult = Null
    jRDC2Utils.Intitialize(rdclink)
    Wait For (jRDC2Utils.ExecuteQuery(jRDC2Utils.CreateCommand("retriveid_postazioni", Array(t_uuid)))) complete (res As DBResult)
    If Not(res = Null) Then
        id = jRDC2Utils.GetColumnObject(res,0,"id")
    Else
        id = Null
    End If
End Sub
Public Sub save() As ResumableSub
    If (id = Null or id.EqualsIgnoreCase("Null")) Then
        wait for (insert) complete()
        wait for (retriveID) complete()
    Else
        wait for (update) complete()
    End If
End Sub
The strange thing is that if I change the name of the method "initialize" (also in all the parts where is called) with whatever else name (i.e.: kinitialize) it works. It seams that "initialize" is like a some kind of reserved word. I could change the name but I've tons of classes with the same method and all have the same problems.
Pls help me.

Thanks for the attention.

Initialize is indeed a special sub. It is similar to a constructor. You shouldn't call it except of when you create the object.

BTW, it is a mistake to set variables to Null, especially string variables.
Thanks Erel,
So I imagine to do a change like this:
B4X:
public Sub initialize(rdcUri As String)
    rdclink = rdcUri
    init

End Sub
private sub init()
    id = ""
    nome = ""
    ubicazione = ""
    t_uuid = ""
end sub
....
Public Sub getPostazioniById(vId As Object) As ResumableSub
    Dim res As DBResult = Null
    jRDC2Utils.Intitialize(rdclink)
    Wait For (jRDC2Utils.ExecuteQuery(jRDC2Utils.CreateCommand("select_postazioni_byId", Array(vId)))) complete (res As DBResult)
    If Not(res = Null) Then
        loadByResultset(res)
    Else
        init
    End If
End Sub
