Hi,
I am getting the above error when I try to generate database scheme.
The error happens after I added the CompositeCustomType.

Here is my class:
public class WorkflowStatus extends BaseObject {
private Integer currentStatus;
private Calendar initialDate;
private Calendar closeDate;
private Calendar dueDate;
private Set approverStatus = new HashSet();

public WorkflowStatus () {

}
.....
}

then I added :
public class WorkflowStatusType implements CompositeUserType {
......

}

I have no idea now what causes the error.

appreciate any help
thanks
lixin

figured out why: public String[] getPropertyNames () and public Type[] getPropertyTypes () did not return the right value.
