In other hand, as you know grails / gorm set ID (primary key) with Long and auto increment by default.

You can replace that by just putting in:<BR/>Date lastUpdated<BR/><BR/>And it will automatically set the time everytime. The documentation about that is under '<BR/><A HREF="http://grails.org/doc/1.0.x/guide/5.%20Object%20Relational%20Mapping%20(GORM).html#5.5.1%20Events%20and%20Auto%20Timestamping" REL="nofollow">Automatic timestamping</A>'Asrihttp://www.blogger.com/profile/16732473266770294267noreply@blogger.com
