Hibernate 执行HQL时出现问题：TransientObject异常

我有一个专业实体，与城市有@manytone单向关系。然后，当执行如下查询时

@ManyToOne(targetEntity=Cidade.class)
@JoinColumn(name="IDE_CIDADE_DOMICILIO_FISCAL",nullable=true)
public Cidade getCidadeDomicilioFiscal() {
    return cidadeDomicilioFiscal;
}

return query.scroll();

…出现此休眠异常。我也尝试过将cascade=CascadeType.ALL包含在proficial端，但没有效果。还有Hibernate的@Cascade注释，如下所示：

@Cascade(CascadeType.SAVED_UPDATE)

没有任何效果

有人能帮忙吗？

没关系
