[vwnc] WSDL: problem marshaling <xsd:any>

Hello,

I currently try to talk to a WSDL service that includes a type with
<xsd:any> content. The relevant types:

<xsd:complexType name="FoundObjects">
<xsd:sequence>
<xsd:element name="object" type="tns:Object" minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>

<xsd:complexType name="Object">
<xsd:sequence>
<xsd:element name="id" type="xsd:string"/>
<xsd:element name="name" type="xsd:string"/>
<xsd:any namespace="##any" processContents="lax" minOccurs="0"
maxOccurs="1"/>
</xsd:sequence>
</xsd:complexType>

the WSDL wizard has created a class for FoundObjects, and uses a Struct
for Object:

FoundObjects>>object: aStruct
<addAttribute: #(#object #optional) type: #(#Collection
#'WebServices.Struct') >
object := aStruct

However, the contents of the Object struct is never marshaled. Given the
following:

object := WebServices.Struct new.
object at: 'id' put: 'foobar'.
foundObjects := FoundObjects new.
foundObjects object: (OrderedCollection with: object).

marshaled as:

<ns:FoundObjects
xsi:type="ns:FoundObjects"
xmlns:ns="urn:schemas.xxx:query"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ns:object xsi:type="ns:Object"></ns:object>
</ns:FoundObjlistType>

tested with VW 7.6

As
object := WebServices.Struct new.
object at: #id put: 'foobar'.
foundObjects := FoundObjects new.
foundObjects object: (OrderedCollection with: object).

See the attached test case.

the WSDL wizard created the following x2oBinding:

<struct name="Object" smalltalkClass="Struct">
<any maxOccurs="1" minOccurs="0" namespace="##any"
processContents="lax"></any>
</struct>

the binding of the testcase includes id/name:

<struct name="Object" >
<element name="id" ref="xsd:string" minOccurs="0" />
<element name="name" ref="xsd:string" minOccurs="0" />
<any aspect="something" minOccurs="0" />
</struct>

with this binding and the correct key (#id instead of 'id'), I can now
successfully (un)marshal id/name - thanks!

However, it seems to be impossible to unmarshal <any> content, e.g.

<object xsi:type="ns:Object">
<weight xsi:type="ns0:float">1.0</weight>
</object>

is unmarshaled as an empty struct. is it possible to (un)marshal such
generic content in any way?

The problem is you need an aspect for <any>. The #aspect is used to create Xpath to unmarchal and get the value from an object to marshal.
<element name="weight" ref="xsd:float" />
<struct name="Object" >
<element name="id" ref="xsd:string" minOccurs="0" />
<element name="name" ref="xsd:string" minOccurs="0" />
<any aspect="weight" minOccurs="0" />
</struct>

You can try <choice>
<struct name="MyChoice" smalltalkClass="Struct">
<choice>
<element name="weight" ref="xsd:float"/>
<element name="int" ref="xsd:short"/>
</choice>
</struct>
<struct name="Object" >
<element name="id" ref="xsd:string" minOccurs="0" />
<element name="name" ref="xsd:string" minOccurs="0" />
<any aspect="myChoice" minOccurs="0" />
</struct>
