Fetch join with pagination fails to append LIMIT in the generated HQL

Hi,

I have an entity

Order 
{
    @Id
    @GeneratedValue
    @Column(name="order_id")
    private BigInteger orderId;

   @OneToMany(mappedBy = "order")
    private Set<OrderLine> orderLines;
}

and bi-directional mapping in entity

OrderLine 
{
    @Id
    @Column(name="order_id")
    @GeneratedValue(generator="gen")
    @GenericGenerator(name="gen", strategy="foreign", parameters=@org.hibernate.annotations.Parameter(name="property", value="order"))
    private BigInteger orderId;

    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "order_id", updatable = false, insertable = false)
    @JsonIgnore
    private Order order;
}

My order repository extends the DataTablesRepository interface. When I had OneToOne mapping the results were fast and the HQL generated had LIMIT in the query. But with the above mapping LIMIT is missing in the query and it takes a long time to fetch all records and then do in memory mapping to return the paginated result.

It’s been more than 3 weeks I am trying to find a work around but not able to figure out how. Can you suggest how can I solve this issue.

@pshingavi @darrachequesne I am facing the same problem. Can any of you provide the solution. I couldn’t find anything in the GitHub link available above.

@darrachequesne Yes, I got this working with the v3.0 version. Thanks a ton for the fix !
