If I try again with valid values (in my case I first entered a too long string for a varchar(50) and then corrected it) I get a sqlalchemy.exc.InvalidRequestError with the info: "The transaction is inactive due to a rollback in a subtransaction. Issue rollback() to cancel the transaction." If I issue the rollback I can commit the session but all the previos entered data is lost. It would be more friendly to try to commit the session and if it fails to let the user change the values and try again.
