HQL: selecting components inside components doesn't work
--------------------------------------------------------

         Key: HHH-2284
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2284
     Project: Hibernate3
        Type: Bug

  Components: query-hql  
    Versions: 3.1.2    
 Environment: Probably all. Tested with DB2, MySQL, HSQL + Tomcat, WAS5, DriverManager.
    Reporter: Fabio Tudone
    Priority: Critical
 Attachments: test.jar

When using an entity with a component owning another component, as follows:

	<class name="org.test.hibernate.bug2455.MyEntity">
		<composite-id>
			<key-property name="myKey">
				<column name="myKey"/>
			</key-property>
		</composite-id>
		
		<component name="myComponent">
			<property name="myValue">
				<column name="myValue"/>
			</property>
			
			<component name="myInnerComponent">
				<property name="myInnerValue">
					<column name="myInnerValue"/>
				</property>
			</component>
		</component>
	</class>

The following HQL query fails:

"select e.myComponent.myInnerComponent from org.test.hibernate.bug2455.MyEntity e"

with the following error:

could not resolve property: myInnerComponent of: org.test.hibernate.bug2455.MyEntity
