EntityHome#getEntityClass() returns EntityManager.class rather than entity class
--------------------------------------------------------------------------------
Key: JBSEAM-2316
URL: http://jira.jboss.com/jira/browse/JBSEAM-2316
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 2.0.0.GA
Reporter: Dan Allen
Priority: Minor
Fix For: 2.0.1.GA
This is a strange one. The getEntityClass() is returning the wrong type parameter. It
should be returning the first but it is instead returning the second.
You will discover that this assertion fails.
assert new EntityHome<SimpleEntity>().getEntityClass() == SimpleEntity.class;

Dan Allen commented on JBSEAM-2316:
-----------------------------------
I'm not even sure its possible with type erasure. You can only get information about
types that are used in the *definition* of a class, not that are supplied a type
parameters when *creating* and instance of the class.
Basically, we need to find another way to do this, or just return null.

-----------------------------------
Sorry, I was completely braindead earlier. Sort of how the day was going. Anyway, this is
to be expected. In fact, the Home class does have logic that deals with the case when the
parameterized type is not available. However, it just misses one case. I have enhanced the
class and expanded the test case to handle/document all scenarios.

This broke the Wiki code that worked in Seam 2.0.0 GA:
public abstract class NodeHome<N extends WikiNode, P extends WikiNode> extends
EntityHome<N> {
}
public class DocumentHome extends NodeHome<WikiDocument, WikiDirectory> {}
The documentHome.createInstance() now creates a WikiDirectory.

-----------------------------------------
Note that the wiki code with the two additional arguments is not in CVS yet. I can
workaround with overriding getEntityClass() if that is the only solution.

[ http://jira.jboss.com/jira/browse/JBSEAM-2316?page=all ]
Pete Muir closed JBSEAM-2316.
-----------------------------
Resolution: Done
It only worked before by chance:
public abstract class NodeHome<N extends WikiNode, P extends WikiNode> extends
EntityHome<P> {
}
public class DocumentHome extends NodeHome<WikiDocument, WikiDirectory> {}
would have guessed the EntityClass as WikiDocument, not WikiDirectory.
So in complex situation's like this you should implement your own getEntityClass()
system (perhaps based on generic inference).
I can't see a better way to handle this given type erasure.
