Hello,
I have an entity that participates in a 3 page wizard-like conversation. However at the end of the third step, calling entityManager.merge on the entity causes this exception to be thrown.

It's id field is generated and assigned before i call merge. Changing it to an autogenerated one (@GeneratedValue) does not make any difference. The entity is annotated with both @In(required=false) and @Out(required=false) in a conversation scope SFSB.

What do you think is wrong?
