Hi John,
ignoring that your clas mappings below do not define <map-to />
directives, the field mapping for Cart's itemsList property should be as
follows:
<field name="itemsList" collection="arraylist" type="Item">
<bind-xml name="item" location="foo/items-list" />
</field>
This should do it.
Regards
Werner

I have a problem similar to that addressed by the 'How to map a
collection of elements'
(http://www.castor.org/how-to-map-a-collection.html). I need to
un-marshal an XML document that contains a collection. The tag at the
collection level is inside another nested tag.
My input XML is:
<cart>
<foo>
<items-list>
<item count="1">broccoli</item>
<item count="4">orange</item>
</items-list>
</foo>
</cart>
I have tried this mapping (and others!):
<mapping>
<class name="Cart" auto-complete="true">
<field name="itemsList" collection="arraylist" type="Item"
container="false">
<bind-xml name="items-list" location="foo" />
</field>
</class>
<class name="Item" >
<field name="Name" type="java.lang.String">
<bind-xml name="item" node="text" />
</field>
<field name="Count" type="java.lang.Integer">
<bind-xml name="count" node="attribute" />
</field>
</class>
</mapping>
I get this error message:
Unable to find FieldDescriptor for 'foo' in ClassDescriptor of cart.
The Cart and Item classes are as per the how-to referenced above.
Please can somebody suggest a mapping that accommodates the "foo" tag?
(Note: my XML is coming from a legacy system and cannot be altered).
Thanks, John
