If you installed QueueMetrics manually with a MySQL Connector/J version 5.x, you may have stumbled into the error:
Errore tecnico nella classe 'it.loway.app.queuemetrics.configurazione.cfg2.ptQueues'.
-- Inner Exception --
- Exception: it.loway.tpf.common.exceptions.TechException
- Stack trace:
- Problema update DB: java.sql.SQLException: !Statement.GeneratedKeysNotRequested!
The error appears when QM inserts a new row, e.g. by creating a new agent or a new queue.
This issue has been fixed for the next major release; if you are encountering it, just use a Connector/J version 3 for the moment.
