For 5 I'd expect hibernate to pick up the "links_id_seq" and fail then on the insert as the sequence is not correctly configured for use with the new, optimized sequence generator. </p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0">The "Link" example is from my JUGs site.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0">Thanks for looking at this,<br> Michael </p> </td>
