Looks like a bug, Mocky - I'll try to duplicate this and make sure it's
fixed. Is this with CVS code or RC1? I did find and correct a couple
more bugs in the course of doing the tutorial, though this doesn't look
like one.
What *should* happen according to the documentation is that you get an
error to the effect that you're trying to use an Object as a Pair. The
map-as requires that the working type of the object can be assigned to
the type associated with the mapping. If you add either item-type="Pair"
on the <collection> elements, or type="Pair" on the <structure
map-as="..."/> element, this should work. I'll add a note on the working
type vs. mapping type to the new tutorial, too.

I'm using a class named 'Pair' which has 2 Strings, a name and a value.
I want to map it to more than one set of XML structures something like
this:
<Response>
<UserProfile>
<GenericAssociation>
<value>IRCMXH</value>
<key>User_ID</key>
</GenericAssociation>
<GenericAssociation>
<value>Habeeb/Mocky</value>
<key>User_Name</key>
</GenericAssociation>
</UserProfile>
<ReturnObject>
<DataElements>
<ObjectDataAttribute>
<name>Record_ID</name>
<value>00584259548</value>
</ObjectDataAttribute>
<ObjectDataAttribute>
<name>Action_Taken</name>
<value>Cancelled</value>
</ObjectDataAttribute>
</DataElements>
</ReturnObject>
</Response>
Where each 'GenericAssociation' would be a Pair, and also each
'ObjectDataAttribute' eventhough one has name/value and the other has
value/key.
To do this I created 2 abstract mappings for class Pair, one named
'value-key-pair' and the other named 'name-value-pair', like this:
<binding direction="both" >
<mapping name="Response" class="AuthResponse">
<structure field="response" map-as="standard-response"/>
</mapping>
<mapping abstract="true" class="ServerResponse"
type-name="standard-response">
<collection name="UserProfile" field="profileValues"
usage="optional">
<structure name="GenericAssociation"
map-as="value-key-pair"/>
</collection>
<structure name="ReturnObject">
<collection name="DataElements" field="dataValues"
usage="optional">
<structure name="ObjectDataAttribute"
map-as="name-value-pair"/>
</collection>
</structure>
</mapping>
<mapping abstract="true" class="Pair" type-name="value-key-pair"
value-style="element">
<value name="value" field="value"/>
<value name="key" field="name"/>
</mapping>
<mapping abstract="true" class="Pair" type-name="name-value-pair"
value-style="element">
<value name="name" field="name"/>
<value name="value" field="value"/>
</mapping>
</binding>
However the binding compiler gives me the following error when direction
is both (it works fine for direction="input"):
*** Error during code generation - please report this error on the JiBX
users list so that the condition can be caught during validation ***

Any suggestions? My java code is below.
Mocky
public class AuthResponse {
private ServerResponse response;
public String toString() {
return response.toString();
}
public static void main(String[] argz) {
IBindingFactory bfact = null;
IUnmarshallingContext uctx = null;
Object result = null;
try {
bfact = BindingDirectory.getFactory(ServerResponse.class);
uctx = bfact.createUnmarshallingContext();
result = uctx.unmarshalDocument(new
FileInputStream("soap.xml"), null);
System.out.println(result);
} catch (Exception e) { e.printStackTrace();}
}
}
public class Pair {
private String name;
private String value;
public String toString() {
return "Pair(" + name + ", " + value + ")";
}
}
public class ServerResponse {
private ArrayList profileValues;
private ArrayList dataValues;
public String toString() {
return "ServerResponse:{profile: " + profileValues + ", data:" +
dataValues + "}";
}
}
