Hi,

I have a entity , which i persist to do DB. This entity is having two Many toMany Relation ship


@ManyToMany
@JoinTable(name = "TCOURSELL", joinColumns = { @JoinColumn(name = "ID_CO") }, inverseJoinColumns = { @JoinColumn(name = "ID_USR") })
private List<User> users = new ArrayList<User>();

@ManyToMany
@JoinTable(name = "TCOANODELL", joinColumns = { @JoinColumn(name = "ID_CO") }, inverseJoinColumns = { @JoinColumn(name = "ID_CON_NOD") })
private List<Node> nodes = new ArrayList<Node>();

Everything is works fine. new member is adding fine with his parents , but unfortunately Em added two same record to db but with the different PK, all other field are same?

Can somebody will sugget me the solution.

Hi,
at first glance I don't see anything wrong.

Could you provide more information, please? Maybe showing the mapping of the other entities and how you persist the object.

Best thing would be to provide a testcase, this would help us to help you a lot faster :)
