Property access and type utilization conflict between runtime and code generation.
-----------------------------------------------------------------------------------
Key: HHH-2581
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2581
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.3
Environment: Fedora Core 6
Reporter: ssarver
Priority: Minor
Attachments: jira.zip

INSTRUCTIONS:
0) Edit hibernate.cfg.xml
1) Run user_ty.ddl
2) Execute: ant test
>>>If code generation is performed with the type attribute
set to the derived UserType
<property name="user" type="test.UserUserType">
<meta attribute="use-in-tostring">true</meta>
<column name="userObject" sql-type="USER_TY"/>
</property>
then hbm2java creates a Person with the derived UserType:
package test;
/**
* Person generated by hbm2java
*/
public class Person implements java.io.Serializable {
private long id;
private String name;
private long age;
private UserUserType user;
public Person() {
}
public Person(String name, long age) {
this.name = name;
this.age = age;
}
public Person(String name, long age, UserUserType user) {
this.name = name;
this.age = age;
this.user = user;
}
...
>>>If code generation is performed with the access attribute set to
the derived UserType and the type set to User:
<property name="user" access="test.UserUserType" type="test.User">
<meta attribute="use-in-tostring">true</meta>
<column name="userObject" sql-type="USER_TY"/>
</property>
then hbm2java creates a Person with the desired User type:
package test;
/**
* Person generated by hbm2java
*/
public class Person implements java.io.Serializable {
private long id;
private String name;
private long age;
private User user;
public Person() {
}
public Person(String name, long age) {
this.name = name;
this.age = age;
}
public Person(String name, long age, User user) {
this.name = name;
this.age = age;
this.user = user;
}
...
However, using the following mapping at runtime:
<property name="user" access="test.UserUserType" type="test.User">
<meta attribute="use-in-tostring">true</meta>
<column name="userObject" sql-type="USER_TY"/>
</property>
produces the error:

>>>Work Around:
Change the name of
hbm/test/Person.hbm.xml.hide
to hbm/test/Person.hbm.xml
and this file to ensure that this mapping definition is
is included in test.jar and not src/test/Person.hbm.xml
This way, at runtime, the following mapping and Person
is being used together successfully:
<property name="user" type="test.UserUserType">
<meta attribute="use-in-tostring">true</meta>
<column name="userObject" sql-type="USER_TY"/>
</property>
package test;
/**
* Person generated by hbm2java
*/
public class Person implements java.io.Serializable {
private long id;
private String name;
private long age;
private User user;
public Person() {
}
public Person(String name, long age) {
this.name = name;
this.age = age;
}
public Person(String name, long age, User user) {
this.name = name;
this.age = age;
this.user = user;
}
