submitAll() : database error

[locus]

I have a new problem , ie.

this thread is in partial relation to the thread "update database" that i initially submitted.

the full code i am using is attached.

Whenever my program attempts to write to the database using submitAll() in the following piece of code:

void submit()
		{
			model->database().transaction();
     if (model->submitAll()) {
         model->database().commit();
     } else {
         model->database().rollback();
         QMessageBox::warning(this, tr("Cached Table"),
                              tr("The database reported an error: %1")
                              .arg(model->lastError().text()));
     }

void submit()
		{
			model->database().transaction();
     if (model->submitAll()) {
         model->database().commit();
     } else {
         model->database().rollback();
         QMessageBox::warning(this, tr("Cached Table"),
                              tr("The database reported an error: %1")
                              .arg(model->lastError().text()));
     }

To copy to clipboard, switch view to plain text mode 

i get the following error:

using unsupported buffer type: -842150451 (parameter: 2) QMYSQL3 : unable to bind value

the QMYSQL3 bit is from the driver, using driverText(), everything before is from the database, using databaseText()

i dont even know what the QMYSQL'3' is about, since i'm not using QT3 support classes. i am thinking the driver is QMYSQL.

If anyone has ever dealt with this error before or have any ideas please let me know.

thanks for your attention.
