    I have model like this. A CLIENT has a related data called FORMATION which based on Product. I need to add this FORMATION to related data field in CLIENT by code (not on GUI in back-end). So here the code i have done. 

    -------------------

    Guid id = new Guid();

                bool tryParse = Guid.TryParse(FormationId, out id);

                if (tryParse)
                {
                    DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();
                    Type clientType = TypeResolutionService.ResolveType(CpModuleClrType.Client);
                    DynamicContent clientItem = dynamicModuleManager.GetDataItems(clientType).Where(c => c.GetValue<string>(ClientField.Nom) == "name").First();

                    // This is how values for the properties are set

                   // Gets error by this line     

                    clientItem.SetValue(ClientField.Favoris, new List<Guid> { id });

                    // We can now call the following to publish the item
                    ILifecycleDataItem publishedArtistsItem = dynamicModuleManager.Lifecycle.Publish(clientItem);

                    //You need to set appropriate workflow status
                    clientItem.SetWorkflowStatus(dynamicModuleManager.Provider.ApplicationName, "Published");

                    // You need to call SaveChanges() in order for the items to be actually persisted to data store
                    dynamicModuleManager.SaveChanges();
                }

    ------------

    The Guid id is the id of a particular formation. When i run this, it keeps getting error "Object must implement IConvertible."

     

    I have tried another way fix this by replacing SetValue by CreateRelation. There was no Error but it didn't save the formation.

     

    How could i change this code to make it works?

    Thanks.
