[jboss-user] [JBoss Seam] - Intercept form data for versioning

I'm trying to build a application that stores changes in a simplified versioning table whenever a change is made. To do this I have a seperate versioncontrol table. To do this I have added a vcUpdate() function to the entityHome class, that stores the state in the versioning table before calling update: public String vcUpdate() { | EntityManager vcEm = this.getEntityManager(); | VcRole vcRole = new VcRole(this.instance, false); | vcEm.persist(vcRole); | vcEm.flush(); | return this.update(); | } But this does not work, as the role I am trying to stored has been changed already. Is there a way to intercept the form data before it is stored? Obviously I don't want to save a copy every time somebody starts the editEntity page, as they might close the session without editing or just press cancel etc. Is there a better way, has anybody done this?
