I've got two acitivities.

Activity A works like a charm
B4X:
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.
B4X:
Sub CheckAfterLast
            CallSub2(Com,"RouteCall","")
End Sub
Function "Routecall" is in a Service "Com"
B4X:
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 = True) Then
'do something
   end if
Error is:
B4X:
Error occurred on line: 817 (Com)

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.
