I'm having trouble with this exception. I have a colection field called patientCollection. The field is of type PatientCollection which extends ArrayList.

The collection mapping in my mapping file is below (called ORUMessage.hbm.xml), which has a uni-directional ref to Patient.hbm.xml.


<bag name="patientCollection" cascade="all">
<key column="patientFK"/>
<one-to-many class="com.orchestral.cdr.element.Patient"/>
</bag>



When reading the error message, I've set hibernate.cglib.use_reflection_optimizer=false in my hibernate.cfg.xml like so:

<property name="hibernate.cglib.use_reflection_optimizer">false</property>

but it didn't really help me get around the original error. The stack trace is below.

This is the code in my ORUMessage.setPatientCollection

public void setPatientCollection(PatientCollection patientCollection) {
this.patientCollection = patientCollection;
}

It appears that Hibernate doesn't like the custom extended PatientCollection type. Can anyone help?

All associations must be of type List/Set, custom implementations don't work.

[quote="michael"]All associations must be of type List/Set, custom implementations don't work.[/quote]

Yeah thanks for that.

Basically instead of the following

public class ORUMessage {
private PatientCollection patientCollection;

public PatientCollection getPatientCollection() {return patientCollection;}
public void setPatientCollection setPatientCollection(PatientCollection patientCollection) { this.patientCollection = patientCollection; }

}

I changed the type to List, like so

public class ORUMessage {
private List patientCollection

public List patientCollection getPatientCollection() { return patientCollection; }
public void setPatientCollection(List patientColelction patientCollection) {
this.patientCollection = patientCollection;

}

Now it seems that I have to lose the PatientCollection class.
