Pete Muir commented on JBSEAM-1969:
-----------------------------------

Sure, I understand the bug.  

I don't understand what you are talking about here

"However, there is one question. The @Create method calls getEntityClass(), which must be non-null and establishes the value of the entityClass private field. That begs the question, should subclasses be forced to call setEntityClass() in the getEntityClass() override?"

and

"However, the same problem will come up if you try to override getId(). I think in that case it is okay to enforce the call to setId() since that is a very special property."

> I am extending an existing class (BookingHome) that extends EntityHome. My BookingHome class needs to override getEntityClass. Doing this then results in a NPE as updatedMessage, deletedMessage and createdMessage refer to entityClass rather than getEntityClass.
