Hi Hervé,
The binding tutorial published with RC1 is unfortunately out of date on
this. I have a newer version of the tutorial that covers it in more
depth, and will be including that in RC2.
To do what you want you just use a <collection> element directly:
<collection field="orders">
<value name="order"/>
</collection>

Hello,
I would appreciate some help regarding the use of arrays of primitive
types.
I've browsed the documentation, it says that arrays of primitive types
are supported.
The question is : what is the proper syntax to describe the mapping ?
Let me take example13 from the tutorial folder found in the distribution.
It contains a Customer class as follows:
public class Customer {
[... other fields omitted for clarity]
private int[] orders;
}
The mapping is defined by using custom methods to (de)serialize an
array of int
And the data format is something like the following :
<customer>
[... other lines omitted for clarity]
<orders>2393901 3119013 3221010 4390901 6501931</orders>
</customer>
This is not precisely what I'm looking for.
I consider int[] (or double[], or whatever primitive array) as a kind
of collection, and I would expect to be able to store (and retrieve)
using the following format :
<customer>
[... other lines omitted for clarity]
<order>2393901</order>
<order>3119013</order>
<order>3221010</order>
<order>4390901</order>
<order>6501931</order>
</customer>
This would be very similar to, say, an ArrayList of Integer, except
that the Java code would be using int[]. Something I need for
efficient computing later on.
Anyone has a suggestion on this :
1/ Is this mapping feasible ?
2/ How do I define it ?
I've tried several definitions like :
<collection field="orders" type="int[]" />
<collection name="order" item-type="int" />
<collection name="order" field="orders" item-type="int" />
<collection item-name="order" field="orders" item-type="int" />
<collection item-name="order" field="orders" type="int[]" /> (I like
this one, even though item-name is not recognized !)
But to no avail so far...
Thanks for any help
