eager fetching of lazy formulas via criteria api

[Alexey Zhukov]

I have simple entity with lazy @Formula property:

public class TestEntity {
    public Long testId;

    @Column(name = "test_id")
    @Id
    public Long getTestId() {
        return testId;
    }

    public void setTestId(Long testId) {
        this.testId = testId;
    }

    private CollectionType custom;

    @Formula(value = "fa.GET_REASONS_NAMES(test_id)")
    @Type(type = "ru.esoft.Platform.hibernatetools.CollectionTypeDescriptor",
            parameters = @org.hibernate.annotations.Parameter(name = "columns", value = "String name"))
    @Basic(fetch = FetchType.LAZY, optional = true)
    @LazyToOne(value = LazyToOneOption.FALSE)
    public CollectionType getCustom() {
        return custom;
    }

    public void setCustom(CollectionType custom) {
        this.custom = custom;
    }
}

I made instrumentation for this class and it works fine.
Sample code for testing:

List list = session.createCriteria(TestEntity.class, "this").
                    setFetchMode("this.custom", FetchMode.JOIN). // fetch me custom please
                    add(Restrictions.idEq(489281L)).list();
            for (Object o : list)
                System.out.println(((TestEntity)o).getCustom());

Unfortunately, the method ((TestEntity)o).getCustom() invokes an additional select-statement for fetching formula:
Hibernate: select this_.test_id as test1_0_0_ from instr_test this_ where this_.test_id = ? Hibernate: select fa.GET_REASONS_NAMES(testentity_.test_id) as formula0_ from instr_test testentity_ where testentity_.test_id=? 489281-10-0005, 489281-10-0004

When i use this code:

List list = session.createCriteria(TestEntity.class, "this").
                    setProjection(Projections.projectionList().
                            add(Projections.property("id")).
                            add(Projections.property("custom"))).
                    setFetchMode("this.custom", FetchMode.JOIN).
                    add(Restrictions.idEq(489281L)).list();

I receive only one select-query execution, but result is List of Object[]. This is not useful.
How can i get List of TestEntities with eagerly fetched custom fields?

PS. Sorry for my English.
