Hibernate assigning incorrect database ID's

Here's the situation: I have a mapping table, let's call it SecurityContact, with three columns.

1. The first column(let's call it security_id) contains the primary key for SecurityContact. Hibernate successfully auto-generates an ID number for this column.
2. The second column(let's call it agent_id) contains the value of the primary key of a second table (let's call it AgentContact), whose primary key column is called contact_id. This agent_id column, with the referenced column contact_id, as you may have guessed, is one of the join columns between SecurityContact and AgentContact.
3. The third column of SecurityContact(let's call it audit_id) also contains the value of a primary key of AgentContact. This is also a join column between SecurityContact and AgentContact, with again the referenced column contact_id within AgentContact. The relationship between entries in SecurityContact and entries in AgentContact is many to one.

So basically, this SecurityContact table connects agent_id and audit_id to security_id. agent_id and audit_id can be the same or different, depending on whether the two entries in AgentContact are the same or different.

Now here's the problem: Even when the two entries are different, Hibernate seems to put the same id for both of them, this id being the contact_id of the auditContact of the SecurityContact. The two entries should be different, with agent_id containing the contact_id of the agent, and audit_id containing the contact_id of the audit (from the same table, AgentContact). Anyone have any idea why?

My apologies in advance for being so long winded. Here is the code for SecurityContact:

 /**

@Entity
@FXClass(kind=FXClassKind.REMOTE)
public class SecurityContact implements Serializable {
    private static final long serialVersionUID = 1L;
    @Transient private String uid;
    @FXIgnore
    public String getUid() {
        if (uid == null) {
            uid = "" + securityId;
        }
        return uid;
    }

    public void setUid(String uid) {
        this.uid = uid;
    }

    }

        return this.securityId;
    }

    public void setSecurityId(Long securityId) {
        this.securityId = securityId;
    }

    public String getCreateDate() {
        return this.createDate;
    }

    public void setCreateDate(String createDate) {
        this.createDate = createDate;
    }

    public String getCreateUser() {

    public void setCreateUser(String createUser) {

    }

    public String getModifyDate() {
        return this.modifyDate;
    }

    public void setModifyDate(String modifyDate) {
        this.modifyDate = modifyDate;
    }

    public String getModifyUser() {

    public void setModifyUser(String modifyUser) {

    public void setAgentContact(AgentContact agentContact) {

    }
    @FXManyToOne(parent="com.counterpartcontacts.entity.AgentContact", property="contactId")

        return this.auditContact;
    }

    public void setAuditContact(AgentContact auditContact) {

}
