Save a message in system store with QMessageService

[grisson]

Hi.
I'm trying to save a message in the system store via QtMobility.

the code is this:

QMessageService *systemMessageService=new QMessageService;
        QMessage *sysMsg=new QMessage;
        QMessageAddress sysNum;
        sysNum.setAddressee(_sendedMsg.getPhoneNumber().toString());
        sysMsg->setBody(_sendedMsg.getText());
        sysMsg->setDate(QDateTime::currentDateTime());
        sysMsg->setParentAccountId(QMessageAccount::defaultAccount(QMessage::Sms));
        sysMsg->setTo(sysNum);
        sysMsg->setStatus(QMessage::Read);
        sysMsg->setType(QMessage::Sms);
        systemMessageManager->addMessage(sysMsg);
        if (!systemMessageService->exportUpdates(QMessageAccount::defaultAccount(QMessage::Sms)))
            showNoticeDialog(QString::number(systemMessageService->error()));

QMessageService *systemMessageService=new QMessageService;
        QMessage *sysMsg=new QMessage;
        QMessageAddress sysNum;
        sysNum.setAddressee(_sendedMsg.getPhoneNumber().toString());
        sysMsg->setBody(_sendedMsg.getText());
        sysMsg->setDate(QDateTime::currentDateTime());
        sysMsg->setParentAccountId(QMessageAccount::defaultAccount(QMessage::Sms));
        sysMsg->setTo(sysNum);
        sysMsg->setStatus(QMessage::Read);
        sysMsg->setType(QMessage::Sms);
        systemMessageManager->addMessage(sysMsg);
        if (!systemMessageService->exportUpdates(QMessageAccount::defaultAccount(QMessage::Sms)))
            showNoticeDialog(QString::number(systemMessageService->error()));

To copy to clipboard, switch view to plain text mode 

The problem is that exportUpdates fails everytime with error code 8 ( QMessageManager::RequestIncomplete ).
No problem with addMessage. it never fails.
I can't find any example on google and i think that i'm forgotting something (incomplete data in sysMsg?).

Any suggestions?

Thanks.
Ivan.
