I have a problem when I am reading the HFEJB Page 396.
It is said that we must NOT try to reference our own persistent RELATIONSHIPS in ejbCreate(). But,it is safe to assign the persistent relationship field in ejbPostCreate().
I cannot understand that.
In ejbCreate() method, the container will use the persistent fields to make the new row in the database. For the CMR field, there should be a corresponding foreign key field in the row. Why, the foreign key field cannot be inserted into the row, together with the other persistent fields?
the row will be inserted in the database after ejbCreate() finishes. So while you are in ejbCreate(), you still dont have data that you are trying to refer. but that row/data will be available in ejbPostCreate() method.
