Ok, thanks I�ll work on it. I did something ugly meanwhile at the session bean so it returns null when there is no object...

Yes, this tag > * target-multiple="yes" says that the relationship is 1:N, not 1:0..1, and that the method should return a Collection or Set. As this is not the case, change it to "no". How that results in the behavior you're seeing I have no idea. Perhaps WebLogic is trying to do something smart by detecting 0 related beans and creating an empty Collection. However, that should result in a ClassCastException at best (or not compile at worst) so I dunno what the deal is.
