B4J Question RuntimeException: Resumable sub already completed - Websocket

[juventino883]

Hi, I'm having a problem with Wait for, the code works in release mode on my computer, but when I have tried to run it on my server I got this error:

I'm calling the waith for from a websocket class using

wait for (organiza_pagos(res)) complete (map_pagos As Map)

and the sub code is this:

Sub organiza_pagos (res As DBResult) As ResumableSub
    Dim map_pagos, map_deudas As Map
    map_pagos.Initialize
    map_deudas.Initialize
    
    
    For Each row() As Object In res.Rows   'crea los maps pagos y deudas
                
        Dim x As Int =0
        Dim tipo_transaccion As String
        Dim numero_transaccion As Int
        For Each record As Object In row
            x=x+1
            If x=1 Then 'numero transaccion
                numero_transaccion=record
            End If
            If x=5 Then 'tipo
                tipo_transaccion=record
            End If
            
            If x=7 Then 'monto USD
                If tipo_transaccion = "PAGO" Then
                    If map_pagos.ContainsKey(numero_transaccion) Then
                    Else
                        Dim p As pagos
                        p.Initialize
                        p.monto_tot=record

                        p.mensualidades=""
                        map_pagos.Put(numero_transaccion,p)
                    End If
                Else
                    If map_deudas.ContainsKey(numero_transaccion) Then
                    Else
                        map_deudas.Put(numero_transaccion,record)

            End If
        Next
        
    Next
    Log("MAP PAGOS ANTES    &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&")
    Log(map_pagos)
    Log("MAP DEUDAS ANTES    &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&")
    Log(map_deudas)
    For i=0 To map_deudas.Size-1
        Dim trans_D As Int = map_deudas.GetKeyAt(i)
        Dim Monto_D As Double =map_deudas.Get(trans_D)
        
            For Each Trans_P As Int In map_pagos.Keys
                Dim p As pagos
                p.Initialize
                p=map_pagos.Get(Trans_P)
                Dim monto_pago As Double = p.monto_tot
                Dim restante_pago As Double = p.restante
                Dim desc_pago As String = p.mensualidades
                If restante_pago>0 Then
                    If Monto_D>0 Then
                        If Monto_D < restante_pago Then
                            restante_pago=restante_pago-Monto_D
                            p.restante=restante_pago
                        desc_pago=desc_pago&" [("&NumberFormat2(Monto_D,1,2,2,True)&"$) "&trans_D&"]"
                            p.mensualidades= desc_pago

                        Else 'monto_D> restante_pago

                            desc_pago=desc_pago&" [("&NumberFormat2(restante_pago,1,2,2,True)&"$) "&trans_D&"]"
                            p.mensualidades=desc_pago
                            p.restante=0
                            Monto_D=diferencia
                        End If
                    map_pagos.Put(Trans_P,p)
                    End If
                End If
            
            Next

        
        
    Next
    Log("MAP PAGOS    DESPUES    &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&")
    Log(map_pagos)
    Log("MAP DEUDAS    DESPUES    &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&")
    Log(map_deudas)
    Return map_pagos
    
End Sub

Sincerelly I don't know if I'm not using the wait for instruction correctly (in the case for websockets) or if it could be a bug? If someone can bringme some light here I will be very greatfull!.

greetings

Why is the sub declared Resumable? There are no Wait For/Sleep statements in the sub. As it stands, instead of

Sub organiza_pagos (res As DBResult) As ResumableSub

you can just do

Sub organiza_pagos (res As DBResult) As Map

And then, instead of

wait for (organiza_pagos(res)) complete (map_pagos As Map)

do

Dim map_pagos As Map = organiza_pagos(res)

Hi Oliver, Thanks for your answer I made those changes and it works!, reading your sugestions, sincerelly I'm asking myself why I have used Wait For ? again thanks for your help!
