    I deployed an application but is crashing at one dialog that maintains a table on a database. The application runs on debug mode and if i run on release mode but from the QT Creator. Correction it doesn't. This dialog is constructed in the same way that other 10 tables. Digging on the net i found a similar problem that suggested that a variable was being overrun, so i started to check if that was possible here and i did fund where the problem was occurring;

    QSqlQuery query;
    query.exec("select * from commodity");
    while(query.next())
      {
        ui->commodity->addItem(query.value(1).toString());
      }
    

    if i comment the ui->commodity->...... line the dialog run but the drop down menu is not filled up. This is the same construction that I have in the other tables and don't understand what could be different from any other table. The only thing different between this table and the others that i made is that when i created the UI by mistake i put a button instead of a drop down menu. After getting an error on the compile i changed the widget but kept the name.
    Has anyone have similar problem?

      Hi,

      Did you check that commodity is a valid pointer ?
      Are you sure the initialisation is done properly ?

        Yes, i have another two tables that also uses the commodity table with exactly the same query to fill up the drop down menus and work perfectly.

          Can you check what differs between the two implementation ?
