I can’t figure out how to pass a complex type to a soap call. I thought  
all you had to do was pass it as a hash, so I could do something like  
this:

result = driver.GetArticle(‘Request’ =\> {‘ArticleId’ =\> ‘20061208’,  
‘Email’ =\> ‘removed\_email\_address@domain.invalid’, ‘Password’ =\> ‘mypassword’})

Unfortunately I always get this error:

SOAP::Mapping::MappingError: nil not allowed: ArticleId

Here is the schema I am working with:

\<xs:complexType name=“GetArticleRequestType”\>  
xs:sequence  
\<xs:element name=“ArticleId” type=“xs:string”/\>  
\<xs:element name=“Email” type=“xs:string”/\>  
\<xs:element name=“Password” type=“xs:string”/\>  
\</xs:sequence\>  
\</xs:complexType\>

\<xs:element name=“GetArticle” type=“tns:GetArticleType”/\>  
\<xs:complexType name=“GetArticleType”\>  
xs:sequence  
\<xs:element minOccurs=“0” name=“Validate” type=“xs:string”/\>  
\<xs:element minOccurs=“0” name=“XMLEscaping” type=“xs:string”/\>  
\<xs:element maxOccurs=“unbounded” minOccurs=“0”  
name=“Request” type=“tns:GetArticleRequestType”/\>  
\<xs:element minOccurs=“0” name=“Shared”  
type=“tns:GetArticleRequestType”/\>  
\<xs:element minOccurs=“0” name=“SubscriptionId”  
type=“xs:string”/\>  
\</xs:sequence\>  
\</xs:complexType\>

Any help would be greatly appreciated
