Hi to all,
I've compiled the following and "same" code:

Qt Code: 
  1. void frmCategorie_AME::inserisciCampi()
  2. {
  3.    QString querySQL;
  4.    querySQL = QString("INSERT INTO %1 VALUES (NULL,:primo,:secondo,1,0)")
  5.       .arg(listaNomiPerTabella["nomeTabella"].toString());
  6.  
  7.    QSqlQuery queryInserimento;
  8.    queryInserimento.prepare(querySQL);
  9.    queryInserimento.bindValue(":primo", ui.lnePrimo->text());
  10.    queryInserimento.bindValue(":secondo",
  11.       ui.cboSecondo->itemData(ui.cboSecondo->currentIndex()));
  12.    if (queryInserimento.exec())
  13.    {
  14.          qDebug() << "INSERT OK!";
  15.          qDebug() << queryInserimento.lastInsertId.toInt();
  16.    }
  17.    else
  18.    {
  19.       QMessageBox::critical(this, tr("Attenzione!"),
  20.          tr("Il database ha riportato un errore: %1")
  21.          .arg(queryInserimento.lastError().text()));
  22.    }
  23.    queryInserimento.finish();
  24. }
To copy to clipboard, switch view to plain text mode 

unbeliveble but the latest version(2009.02) give me back the following error:

Qt Code: 
  1. src\frmCategorie_AME.cpp: In member function `void frmCategorie_AME::inserisciCampi()':
  2. src\frmCategorie_AME.cpp:15: error: insufficient contextual information to determine type
  3. make[1]: *** [debug/frmCategorie_AME.o] Error 1
To copy to clipboard, switch view to plain text mode 

qDebug() << queryInserimento.lastInsertId.toInt(); == insufficient contextual information to determine type

HELP!!!
