    I've got two acitivities.

    Activity A works like a charm
    Code:
    Sub oBtn_Click
             
    CallSub2(Com,"Routecall","")
    End Sub
    In Activity B I've the following (exactly the same) but called from a button in activity B.
    Code:
    Sub CheckAfterLast
                
    CallSub2(Com,"RouteCall","")
    End Sub
    Function "Routecall" is in a Service "Com"
    Code:
    Sub RouteCall(XMLparameters As String'As Int
        Dim requestSoapXML As String
        
    Dim sChar As String
        
    Dim Soap As HttpJob
        
    Dim i, iReturn As Int
        XMLparameters = Globaal.String2Base64(XMLparameters)
        XMLparameters = 
    "||"&XMLparameters
        XMLparameters = Globaal.String2Base64(XMLparameters)
        sChar = 
    "&"
        iReturn=
    0
        requestSoapXML = Globaal.MainUrl&
    "/Getdata13/JSON?ipar="&Globaal.par1&sChar&"spar="&Globaal.par2
        
    If Globaal.DoLog=1 Then Log(requestSoapXML)
        Soap.Initialize(
    "GetRoute",Me)
        Soap.Download(requestSoapXML)

        
    wait for (Soap) jobdone(Soap As HttpJob'<<<<<< fails on this line when from Activity B
        If (Soap.Success = TrueThen
    'do something
       end if
    Error is:
    Code:

    Why does the first action work and the second doesn't?

    I'll try to get it in a smaller version. There are some login details I can't send you.
