How do I populate a process datafield from an infopath XML field?

As of this writing the Simple Data Mapper wizard event is not yet available for BlackPearl.  For now, within a default server code event it is relatively easy to pull data from your XML fields into your process datafields.  Use the following code, customizing your SchemaName for the text SchemaName below.  You would need an XML field called Notes and a Process Datafield called Notes for this to work.

          //substitute your SchemaName here (K2ObjectBrowser>DataTab>XMLFields>the one below "activities" is your SchemaName)
          string XMLString = K2.ProcessInstance.XmlFields["SchemaName"].Value;

          //the double slash "//" in the XPATH makes the xmlhelper search for the field name, if you had more than one Notes fields you would need a more concise XPATH
          K2.ProcessInstance.DataFields["Notes"].Value = SourceCode.Workflow.Common.XmlHelper.GetXPathValue(XMLString, "//my:Notes");

Hope this helps,
