These are fundamental things but I can't them clear from documentation, indeed.
Please throw some light at least to the following.
Entity beans are stated to have CONVERSATION scope by default.
If managing component is scoped to SESSION, and CONVERSATION-scoped entities are fields of this component - what happens to them when conversation ends but session continues ?
Depends if they are @In fields or not.
(1) If they are @In fields, they always refer to the entity in the current conversation
(2) otherwise, they are just Java object references. Nothing "special" happens
