I created Hibernate entity classes from NetBeans master. All works Ok except if I open detail entity by HQL then master will be empty (all fields will be null, '' or 0). I use Hibernate 4.3.
Example:
in master (DealerMain):
@OneToMany(fetch=FetchType.LAZY, mappedBy="dealerMain")
public Set<AccountMain> getAccountMains() {
return this.accountMains;
}

in detail (AccountMain):
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="GroupID", nullable=false)
public DealerMain getDealerMain() {
return this.dealerMain;
}

If I open AccountMain by HQL then all fields in AccountMain.getDealerMain() will be empty. SQL operator right.
But if I'll open before DealerMain (dealer of the account) then dealerMain will be right.
I looked in debugger what wrong master if used Hibernate generated class derived from DealerMain.
Any suggestions?

Thanks,
Haim Fridland.
