Using only this code ``` KNS3::UploadDialog dialog(QStringLiteral("ksysguard.knsrc")); dialog.setUploadFile(QUrl::fromLocalFile(currentWorksheet->fullFileName())); ``` the upload dialog comes up on the upload step with the back button enabled, clicking the upload button raises an error about an invalid categeory (which is invalid because it was never set...).
