Andy Dale commented on HHH-2159:
--------------------------------

Jesper,

As far as i can see the there are only 2 places where fromElementByClassAlias.put() is called.  The first place is in registerFromElement, but if the value to be put is null then no put takes place, the second is in addDuplicateAlias which orignally put whatever was passed to it (including null) in the fromElementByClassAlias Hashmap.  

Assuming you have added the if statement stopping null values (key values) getting into the fromElementByClassAlias Hashmap in the addDuplicateAlias method I cannot see how null has managed to be be put as a key in the Hashmap.

Hibernate team, are these the only 2 places where values are put into the fromElementByClassAlias Hashmap ???

Cheers,

Andy

>          Issue Type: Bug
>    Affects Versions: 3.2.0.ga
>         Environment: hibernate 3.2.0GA, PostgreSQL 8.1.4 (using build 407 of the JDBC driver).  JDK 1.5.0_06, JBoss 4.0.4GA, Operating system is Fedora Core 5

> First off i do not know if this bug belongs to the Hibernate3(core) or Hibernate EntityManger branch, but have entered it against core because that is where the exception occurs (in org.hibernate.hql.ast.tree.FromClause.findIntendedAliasedFromElementBasedOnCrazyJPARequirements).
> I have a relativley simple entity setup up to test a proof of concept.  Persisting the data to the database is not a problem in the new version 3.2.0.GA, but the problems occurs when trying to perform a query on the persisted data, the very same query works with 3.2.0CR2 but gives a nullPointException in 3.2.0GA.
> I have attached the java source for the entities + session bean (in hibernate_testcase.tar.gz/entities file) and the java class (in hibernate_testcase.tar.gz/service file) that is used to persist and query the data, and because this was only meant to be a proof of concept i have also included the .ear archive as apart from the entity definitions and session bean the only other thing it contains is a JBoss .sar archive which calls the static persist and query methods in the session bean (service test.testcase).  Please note to use the .ear archive you need a datasource called Postgres_Test
