Hi,
Was not getting this error while using Hibernate earlier versions. Upgraded to Hibernate core 3.6.0.Final and Search 3.3.0.Final.
I am using a complex data model and come across this error while deleting a child collection entity manually. The model is:

Parent entity:
Code:
@Entity
@Indexed
public class Company extends MR{
    @OneToMany(mappedBy = "company", cascade = { CascadeType.REMOVE } )
    @org.hibernate.annotations.Cascade(value = org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
    @Sort(type = SortType.NATURAL) @Cache(usage=CacheConcurrencyStrategy.READ_WRITE)   
    @LazyField
    @IndexedEmbedded
     private Set<Employee> contacts = new TreeSet<Employee>();
....
}


Child entity:
Code:
@Entity
@Embeddable
public class Employee{
   @ManyToOne @NotNull
   @JoinColumn(name = "COMPANY_ID") @Index(name = "COM")         
   @ContainedIn
   private Company company;
....
}


No cascade all to prevent slowness when the user changes just a single Employee and the record updates 1000's of Employee while saving the Company record. I am manually adding/updating the child entity. But when I remove the child entity, I get this error:
Removing manually
Code:
for (Employee emp : emplist) {
Employee temp = Employee .findById(emp.getId(), Employee .class);
temp.remove();
}


Code:

Hi,

the exception complains about an entity com.x.y.z.company.Contact which you don't even mention in your model. Where does it fit into your model?

Sorry about that. Its the Employee class. I didn't quote the example well.

When I add the Employees and save them manually, and then save the Company, its works fine. This happens only when I try to remove one or more Employees from Company. When I manually delete the Employee, its throws this exception.

Is it possible that this child object was never indexed and that's why it complains as unable to find the Entity? I tried indexing Employee while saving. Still got the same error while deleting.

You code is missing the actual session code and how you manage the session and transaction. It would be best if you could condense this down to a unit test so that we can re-produce the problem.

I am wondering whether you have the Company containing the Employee still in the same scope. Since you are not removing the employee from the contacts set the company instance might be in an inconsistent state at this point.
