Repeated Elements in DataSet Schema

Hi,

I am trying to receive XML via a web service in InfoPath. I have used this article which does exactly what I want to do http://blogs.msdn.com/infopath/archive/2007/02/05/infopath-and-yukon-the-details.aspx and the example works fine with a very simple Schema. The article describes how to pass a DataSet object over the web service. The problem comes when I try to use a nested repeated structure in my schema for example:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="TestRoot">
  <xs:annotation>
   <xs:documentation>Comment describing your root element</xs:documentation>
  </xs:annotation>
  <xs:complexType>
   <xs:sequence>
    <xs:element name="TestElement">
     <xs:complexType>
      <xs:sequence>
       <xs:element name="Value" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>
      </xs:sequence>
     </xs:complexType>
    </xs:element>
   </xs:sequence>
  </xs:complexType>
</xs:element>
</xs:schema>

When I try to connect to InfoPath using the "connect to a data source" I get the following error:

"InfoPath cannot design a form based on this operation because it uses a DataSet which contains a column with SimpleContent column mapping."

I have tried to use a strongly-typed DataSet instead of assigning the schema a run-time and I get the same error. I know that what I am trying to do is possible in InfoPath (perhaps by a completely different method) but I can’t seem to get it to work.

Please could someone help me with my specific error or give me a more general solution/ methodology if I am going in completely the wrong direction?

Thanks,

Jamie
