I am trying to programmatically update the value in one or more instances of a recurring calendar event series using Nintex Workflow 2010. (I know that if I do this through the UI it will remove the updated items from the series, and this outcome would be acceptable.)
I can use the GetListItems method of the Lists.aspx web service to query the event for all its recurring instances. This returns an XML document with a root node of listitems, with unique EventDates and IDs for each member of the series. I therefore expected to be able to update one or more of these items using the UpdateListItems method of the same web service but everything I try updates ALL the events in the series instead of the ones I am trying to update. Is there a way to do what I'm attempting?
Thanks, in advance.
