Re: [JBoss-user] How to INSERT after ebjPostCreate versus ejbCreate
Dain, I did a hunt on google for any problems, and the only thing I found was this: www.geocities.com/lydian_third/ admintips/pkconstraint.pdf Basically it seems that unique indexes may cause a problem with deferrable constraints. However, I think the way we use the deferrable fk constraint, then it should be OK.

Re: [JBoss-user] How to INSERT after ebjPostCreate versus ejbCreate
Rod, If you are using Oracle as your DB, then you can mark your CMR fk columns as DEFERRABLE INITIALLY DEFERRED. Oracle will only check the non-null constraints at commit time. Shouldn't be a problem for you. Other DBs may have something similar.
