Hi Stephan,
I`m using the mapping file as this appears to be the most flexible
option for our needs.
What I`m actually trying to do is map 2 elements to a single method
,which is a collection, in a class.
So my XML looks like:-
--------->ElementB
ElementA---|
--------->ElementC
In my Java code I would like to add both Elements B and C to the same
collection as ElementB and C Map to classes that derive from the same
interface. So in my mapping I tried to do something like:-
<field name="items" type="itemInterface" required="false" direct="false"
transient="false" collection="arraylist">
<bind-xml name="itemB" node="elementB"
reference="false" />
<bind-xml name="itemC" node="elementC"
reference="false" />
</field>
But this is invalid as there can be only one <bind-xml> tag within a
field.
I also tried to add 2 fields to the mapping file referencing the same
"items method" like:-
<field name="items" type="itemInterface" required="false" direct="false"
transient="false" collection="arraylist">
<bind-xml name="itemB" node="elementB"
reference="false" />
</field>
<field name="items" type="itemInterface" required="false" direct="false"
transient="false" collection="arraylist">
<bind-xml name="itemC" node="elementC"
reference="false" />
</field>
But when I tried to Marshall an Exception was thrown stating that there
was duplicate method names in the mapping file.
So is it possible to map 2 XML Elements to one method in a Java class???
Thanks for your help.

Darran-
Just to clarify, are you attempting to use a binding file to generate
classes from your schema? Or are you using a mapping file to generate
the XML using the existing java classes?
In the later case, it should be pretty easy to get it set up using the
InterfaceA, at which point Castor doesn't need to know much about ClassA
or ClassB. If you're attempting to use the binding file, I
unfortunately don't know much about that.
Thanks,
Stephen
