NPE when using composite-map-key and composite-element together in a map
------------------------------------------------------------------------
Key: HHH-3689
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3689
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1
Environment: 3.3.1, MySQL 5
Reporter: Jason Maskell
When trying to get a composite map key working with my composite element class, I ran into
this issue. I've seen it reported in a couple of other places since August 08, so
it's been around for a while.
<map name="inventory" table="capo_inventory">
<key column="capo_id"/>
<composite-map-key class="ItemCountKey">
<key-many-to-one name="item" column="item_id"
class="Item"/>
<key-property name="quality" type="int"
column="quality" />
</composite-map-key>
<composite-element class="ItemCount">
<many-to-one name="item" class="com.tamedtornado.data.Item"
formula="item_id" />
<property name="quality" formula="quality" type="int"
/>
<property name="count" type="int" />
</composite-element>
</map>
This mapping causes this error (root cause):

It's quite easy to debug, but I have no idea what it's supposed to be doing, so
have no idea how to fix it. The String[] cols parameter passed into
walkCompositeElementTree has two nulls in it, which causes the NPE later in the stack. I
hope this is easily reproducible, as I'm going to have to write some really grodey
code now that I can't easily find my object by those two parameters. :)

------------------------------------
This issue is not just related to composite elements. I got this using Hibernate 3.3.1 and
Annotations 3.4. I will try to provide a test case.

-------------------------------
I experience same problem using Hibernate 3.3.1.GA (on DB2 AS400) with XML Mapping, using
formula within many-to-one and composite-element
I read the source code org.hibernate.loader.JoinWalker, and I make some changes and seem
work fine.
within the walkCompositeElementTree() method line 522
// simple, because we can't have a one-to-one or a collection
// (or even a property-ref) in a composite-element:
// String[] aliasedLhsColumns = StringHelper.qualify(alias, lhsColumns);
String[] fullAliasedLhsColumns = persister.getElementColumnNames(alias);
String[] aliasedLhsColumns = ArrayHelper.slice(fullAliasedLhsColumns, begin, length);
by commenting original line "String[] aliasedLhsColumns = StringHelper.qualify(alias,
lhsColumns);", then add following 2 lines
String[] fullAliasedLhsColumns = persister.getElementColumnNames(alias);
String[] aliasedLhsColumns = ArrayHelper.slice(fullAliasedLhsColumns, begin, length);
The table that is mapped to, is only used for immuture table (read-only), so I guess it
would work fine for me. Not sure if this "trick" would apply for update, insert
or delete operation.
If anyone from Hibernate can confirm this, it would be great.
I hope this help.
