Custom code development using CMIS

[amittongaonkar]

Hello All,

I am developing a custom .NET based application which needs to interact with the Alfresco system in place. I want to retrieve all the versions of a particular document along with all their metadata and pass them to my custom application.

I have written following code, but its giving me "Bad Request" error. I think I am getting error where there is some mismatch in the RepositoryId and ObjectId that is getting passed. I need your kind help to fix the same.

private IItemEnumerable<ICmisObject> GetChildren(IOperationContext context)
                    {
                        string objectId = "1a8fefd8-d99c-4df2-9a44-e66e2cadea2d";
                        INavigationService service = session.Binding.GetNavigationService();
                        IObjectFactory of = session.ObjectFactory;
                        IOperationContext ctxt = new OperationContext(context);
                        String folderId = session.GetObject("workspace://SpacesStore/0270f45a-b41a-41af-bab8-4951234817b9").Name;

                        service.GetFolderTree(session.RepositoryInfo.Id,"0270f45a-b41a-41af-bab8-4951234817b9",1000,context.FilterString,context.IncludeAllowableActions,context.IncludeRelationships,context.RenditionFilterString,context.IncludePathSegments

IObjectInFolderList children1 = service.GetChildren(session.RepositoryInfo.Id, objectId, context.FilterString, context.OrderBy, context.IncludeAllowableActions, context.IncludeRelationships, context.RenditionFilterString, context.IncludePathSegments, 10, 0, null);
                        PageFetcher<ICmisObject>.FetchPage fetchPageDelegate = delegate(long maxNumItems, long skipCount)
                        {
                            IObjectInFolderList children = service.GetChildren(session.RepositoryInfo.Id, objectId, context.FilterString, context.OrderBy, context.IncludeAllowableActions, context.IncludeRelationships, context.RenditionFilterString, context.IncludePathSegments, maxNumItems, skipCount, null);

                            // convert objects
                            IList<ICmisObject> page = new List<ICmisObject>();
                            if (children.Objects != null)
                            {
                                foreach (IObjectInFolderData objectData in children.Objects)
                                {
                                    if (objectData.Object != null)
                                    {
                                        page.Add(of.ConvertObject(objectData.Object, ctxt));
                                    }
                                }
                            }

                            return new PageFetcher<ICmisObject>.Page<ICmisObject>(page, children.NumItems, children.HasMoreItems);

                        };
                        return new CollectionEnumerable<ICmisObject>(new PageFetcher<ICmisObject>(context.MaxItemsPerPage, fetchPageDelegate));
                    }

Hi Amit,
What is your DOTCMIS version? If possible, please post your complete class file.

Hi Amit,
Please try this and let me know.
To retrieve all the versions of a particular document.

            Dictionary<string, string> parameters = new Dictionary<string, string>();
            parameters[DotCMIS.SessionParameter.BindingType] = BindingType.AtomPub;
            parameters[DotCMIS.SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/service/cmis";
            parameters[DotCMIS.SessionParameter.User] = "admin";
            parameters[DotCMIS.SessionParameter.Password] = "admin";
            SessionFactory factory = SessionFactory.NewInstance();
            ISession session = factory.GetRepositories(parameters)[0].CreateSession();
            // get the document using its noderef
            Document document = ((Document)session.GetObject("workspace://SpacesStore/b49fb618-76a1-4f19-91ac-37c8c39a2412"));
            IList<IDocument> documents = document.GetAllVersions();

            foreach(Document doc in documents )
            {
                Console.WriteLine("Document name : " + doc.Name + " and its version " + doc.VersionLabel);
            }
