Description

The following code should work but fails with a "Value cannot be set on Element" error.

    class Program
    {
        static void Main()
        {
            const string description = "this is a new description";

            parameters[SessionParameter.AtomPubUrl] = "http://localhost:8082/alfresco/service/cmis";
            parameters[SessionParameter.User] = "admin";
            parameters[SessionParameter.Password] = "admin";
            parameters[SessionParameter.RepositoryId] = repositoryId;

            SessionFactory factory = SessionFactory.NewInstance();
            ISession session = factory.CreateSession(parameters);

            string changeToken = null; // not sure why I need this

            Properties props = new Properties();
            props.Extensions = CreateData(description).Extensions;
            session.Binding.GetObjectService().UpdateProperties(repositoryId, ref documentId, ref changeToken, props, null);
        }

                                                            {"displayName","Description"},
                                                            {"queryName","cm:description"}

                                                                {
                                                                    Name = "cmis:value",
                                                                    Namespace = "http://docs.oasis-open.org/ns/cmis/core/200908/",
                                                                    Value = description
                                                                }
                                                        }
                                            }
                                    }
                            }
                    }
                };
            data.Extensions.Add(element);

            return data;
        }

The following change in converter.cs, line 1869 in Converter::CreateXMLElement(XmlDocument doc, ICmisExtensionElement element) should be made:

result.Value = element.Value;
// should be
result.InnerText = element.Value;
