[jboss-user] [JBoss Seam] - Re: save the transient instance before flushing

[squ1rr3l]

I'm getting a similar error, and as a SEAM newbie, I can't figure out how to fix it.

I used seam-gen to create a new project, then used new-entity.  The resulting components allow me to create and edit, but the "delete" button produces the TransientObjectException:

16:08:25,384 ERROR [ExceptionFilter] exception root cause
