CSenServiceConnection SetStatus with status -1

[serickson@fb-4.com]

I am using CSenServiceConnection to send the xml request. But my SetStatus in some devices always called with status -1 which is KSenConnectionStatusCreateFailed. here is fragment of my code:

servicePattern = CSenServicePattern::NewLC(KSoapServer, KNullDesC8);
servicePattern->SetFrameworkIdL(KDefaultBasicWebServicesFrameworkID);
servicePattern->SetContractL(KPpContract);
iConnection= CSenServiceConnection::NewL(*this,*servicePattern);

In some devices, it works fine. But in other devices, the SetStatus is been called with status as -1.
I also tried to add the following before the creation of iConnection:

servicePattern->SetConsumerIapIdL(1)

But it is the same result.

Please help me out!
TIA
