Updating a Business Object from XML
I'm trying to update an Item through the method <b>GetBusinessObjectFromXML</b> but I obtain always the message "The object's key is not set".
On the other hand the insert action works fine.
I think this is because I have not read previously the Item with <b>GetByKey</b>; but if I do this, how can I update the business object with the data in the XML?
Can anybody help me?
Thanks in advance.
