I mean to add some clarification to the docs on this. The use of CONVERSATION-scoped or SESSION-scoped Entity Bean Seam components is not considered truly cluster-safe. If you need to be cluster safe, hold the reference to the entity bean inside a stateful session bean (in any version of Seam) or inside a JavaBean Seam component that implements Mutable (in Seam 1.1). This is why we recommend the use of stateful session beans: they are the best way to achieve cluster-safe-ness of conversation-scoped state.
