Exposed Orchestration as WS; Can’t send XML with multiple records??

HI all,

I have an orchestration which is suppose to accept an XML with multiple child records…but when I expose the orchestration and schema's as a web service, the schema objects are offered as array objects..which is fine, I can map the data in using a loop, but when it comes time to pass in the final XML to the orchestration/web method, the schema parameter expects to know the array index number of the message to send in…I don't want that as I want to send all records, not just one.

I tried creating an untyped web service in the following 'walk through':
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/BTS_2004WP/html/5cab05ab-6848-4f6c-8d11-9abc4dd1d1fa.asp
but had no luck as the parameter to pass in is an XmlNode…and I also don't have a response as the web method errors saying that it does not produce a value.

Help!
