Process data extraction

Migrateduser

I am creating a process data archive for a customer using TCP 10.0.1.

I have created a utility which for a specific process instance ID will connect using the TCP web services API and obtain the _default data object which is returned as an XML document object which i am able to parse into a SQL data set for writing out the data set to a sql database table.

I now need to do the same transfer of the _default data object from the code behind on the workitem web form.  Here i am using the TCP client API and have the ProcessInstance object and can use the getfield method to get the individual data attributes but would like to get the whole _default data object as XML as returned by the web service API.

Is this possible or do i need to reference and call the web service API from the code behind?

Thanks
