Hi Folks,
I've re-read the following page:
http://jakarta.apache.org/ojb/tutorial3.html#setting%20load-,%20update-%
20and%20delete-cascading
Should there be any reason why I should not expect load-cascading to
load an _entire_ object graph?
For example, I have an Order class, with a collection of OrderDetails,
and each OrderDetail contains an Item. Loading the Order object
populates the OrderDetail collection, however none of the OrderDetail
objects have an Item (null) when I retrieve the order.
Here's a snippet from my class:
Order order = new OrderBean();
order.setId(Integer.parseInt(orderid));
Query query = new QueryByExample(order);
order = (Order) broker.getObjectByQuery(query);
Here's a snippet from my repository.xml:

Am I missing something?
