Hibernate: Found Shared References to a Collection

[David Zazeky]

I started with the following three tables:

Customer

Roles

Customer_Has_Roles

In the Customer.hbm.xml, I have the following:

<set name="roles" table="Customer_Has_Roles" lazy="false" fetch="join">
	<key column="customerId" />
	<many-to-many column="roleId" class="org.myCompany.Role" fetch="join" />
</set>

In the Role.hbm.xml, I have the following:

<set name="customers" inverse="true" table="Customer_Has_Roles">
	<key column="roleId" />
	<many-to-many column="customerId" class="org.myCompany.Customer" />
</set>

The above configuration is working in my application, but I want to add a new many-to-many table called Admin_Has_Roles between the Admin and the Roles table. In the admin.hbm.xml file, I added the following:

<set name="roles" table="Admin_Has_Roles" lazy="false" fetch="join">
	<key>
		<column name="adminId" />
		<column name="employeeId" />
	</key>
	<many-to-many column="roleId" class="org.myCompany.Role" fetch="join" />
</set>

I did not add a new set to the Role.hbm.xml file since I don't want the Customer table to inherit the Admin_Has_Roles relationship. When I try to save an Admin object in my application, I now get the following Hibernate exception:

org.springframework.orm.hibernate3.HibernateSystemException: Found shared references to a collection: org.myCompany.roles; nested exception is org.hibernate.HibernateException: Found shared references to a collection: org.myCompany.Admin.roles

What am I doing wrong with my hibernate config? Why can't I create a many-to-many relationship between Admins and Roles?
