[vwnc] Wrong object returned from Soap call

After a long strugle I finally was able to communicate with the
salesforce.com wsdl service. I'm trying to see if Smalltalk would make
a good replacement for VB or C# which are well supported.

Problem I run into is that running a query can return different types
of objects. In Java or C# one would use a typecast to convert the
object to the right type. For example a query of the user table
returns User objects, which extend the generic SObject. Problem is
that the wsdlclient returns the generic SObject and not the User
object.

The WSDL code shows something like:
- <complexType name="sObject">
- <sequence>
<element name="fieldsToNull" type="xsd:string" nillable="true"
minOccurs="0" maxOccurs="unbounded" />
<element name="Id" type="tns:ID" nillable="true" minOccurs="0"
maxOccurs="1" />
</sequence>
</complexType>
- <complexType name="User">
- <complexContent>
- <extension base="ens:sObject">
- <sequence>
.........

Is there any way to get the xml marshaller to recognize the right
object type or is that beyond the vw wsdl toolkit capabilities?

Thanks,

Frank

Re: [vwnc] Wrong object returned from Soap call

You could take a look at XMLObjectMarshalingManager class comments.
There is #AllowDerivedTypes shared variable that allows marshaling
derived objects when a type is described with a super class marshaler.
You set the option from VW Settings->Web services->XMLObject Marshaling
