[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1969) updatedMessage, deletedMessage and createdMessage in framework.Home cause NPE if getEntityClass is overridden
[ http://jira.jboss.com/jira/browse/JBSEAM-1969?page=comments#action_12380140 ]
Dan Allen commented on JBSEAM-1969:
-----------------------------------
If you override getEntityClass() to provide your own return value, it will lead to a
NullPointerException when you call one of the message convenience methods because they
reference the private field entityClass from the parent class Home. Since the subclass
does not have access to this field (other than calling setEntityClass()), it remains null.
This fix has those methods use getEntityClass() rather than the field directly, allowing
the convenience methods to utilize the overridden method.
I have a test case as well. Attaching.

Key: JBSEAM-1969
URL: http://jira.jboss.com/jira/browse/JBSEAM-1969
Project: JBoss Seam
Issue Type: Bug
Components: Framework
Environment: Mac OSX 10.4.8, Jboss 4.2.1, Seam 1.3.0
Reporter: Damian Harvey
Assigned To: Dan Allen
Priority: Trivial
Fix For: 2.0.1.GA
Attachments: JBSEAM-1969-v1.txt
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.
