I am assuming your entity beans are BMP, since you are explicitly modifying bean state
(which subsequently need to be persisted) in your ejbCreate/ejbPostCreate methods.
Well, my point is if you compare the lifecycle of accessing a bean method:
EJBObject.methodA()
Bean.ejbLoad()
Bean.methodA()
Bean.ejbStore()
versus creating a new bean/row:
EJBObject.create()
Bean.ejbCreate()
Bean.ejbPostCreate()
You'll notice that there is no ejbLoad/Store wrapping a create. Hence the onus is on
ejbCreate/postCreate to perform all the persistence calls (for bmp). If you modify the
state of the bean in ejbPostCreate, then you also have to make the persistent calls for
them to stick. Otherwise who else is going to do the job?
