Hello everybody,

I've came across some issues while trying to use a one-to-many relationship with inverse="false".

Let's have a look at my POJOs.

First the POJO corresponding to the parent in the one-to-many relationship :

public class Service extends BaseObject
{
private Set contacts = new HashSet();

/**
* Adds a contact to a service
* @param contact Le contact

Show your mapping files.

Here are my mapping files :

SERVICE
