[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Lazy Loading of Map key For OneToMany

[calidoggg]

Hi,

I am using maps to represent a one-to-many relationship in our entity:

    @OneToMany(cascade = CascadeType.ALL, mappedBy = "patientID")
  |     private Map<Integer, OrderTable> orderTableCollection;

This is a snippet of the Patient entity, which has a one to many relationship with the OrderTable entity.

I am going to be detaching this entity from the J2EE server.  Since this is a oneToMany relationship the Map is lazily loaded by default (this is the behavior that I want, I DO NOT want to eagerly load it); does this mean the Map might not be instantiated? Or will the Map be instantiated with the proper OrderTable keys but not the corresponding OrderTable entity values?

Thanks.
