I have following mappings:

public class Country implements Serializable {

	private String id;

	@OneToMany(mappedBy="country", cascade=CascadeType.ALL, orphanRemoval=true)
	private List<CountryLocale> countryLocales;
	        joinColumns=@JoinColumn(name="COUNTRY_ID", referencedColumnName="ID")
	private List<String> timezones;

public class CountryLocale implements Serializable {

    private Country country;
	private String locale;
	    	        @JoinColumn(name="COUNTRY_ID", referencedColumnName="COUNTRY_ID"),
	    	        @JoinColumn(name="LOCALE", referencedColumnName="LOCALE")
	private List<String> fallbackLocales;

Then i do the following:

    Country c = em.find(Country.class, "DE");
    for (String tz: cl.getTimezones()) {
    for (CountryLocale cl: cl.getCountryLocales()) {

The timezones are printed in the correct order.
BUT the CountryLocale are printed unsorted! (in the same order the database put them into the resultset).
Is it a bug or do I do something wrong?

I tested it with eclipselink 2.0.1 and 2.1.0-M6.

The OneToMany should get ordered based on the index column "OrderIdx" is the table.

It could be a case issue. Try using "ORDERIDX".

Otherwise please include the SQL, data results, and resulting object order.
