I have a standard Order - OrderLine relationship whereby the OrderLines run in
the thousands and they contain binary data up to about 5 MB in data per
OrderLine. Obviously I don't want to page them in all at the same time.
I have annotated my method with everything I could find:
| @OneToMany(cascade = { CascadeType.PERSIST, CascadeType.REMOVE })
| @IndexColumn(name = "index", base = 0)
| @LazyCollection(LazyCollectionOption.EXTRA)
| @JoinTable(
| name = "order2orderlines",
| joinColumns = @JoinColumn(name="order_id"),
| inverseJoinColumns = @JoinColumn(name="order_line_id")
| )
| public List<OrderLine> getOrderLines() {
| return orderLines;
| }
|
Everything works fairly well. getOrderLines().size() does a nice select that
counts (based on the index column), getOrderLines().get(i) nicely loads up the
the one item I want.
When I try to add an item using getOrderLines().add(orderLine) however, the
world comes to an end -- the whole list is paged in. Is there any way around
this other than just managing the list myself through queries?
This is with the JBoss CVS checkout of 2006-06-13 but I've been having this
problem for a while now.
