Thank you for your quick reply. But I don't understand what's going wrong.

When doSomething of Bean2 is called from an other tier, a new transaction should be created. When in doSomething the method findEntity of Bean1 is called the same transaction should be used and no new one should be generated, because the default transaction type is REQUIRED. So I think that the persistence context should be bound to this transaction and the returned entity should not get detached, but it's not like this. 

Any ideas why this happens?
