I upload a annotation, but its empty

(0) ShareShare

Posted on by _Lars_ 225

I'm able to create records of entities and want to upload annotations (file attachments) but while the annotation is created and I get the GUID for the annotation, its completely empty holding no data.

I implemented, actually copy & pasted, the code from SDK\SampleCode\CS\BusinessDataModel\Annotation in samples in the SDK. Are there any other tricks to it? As mentioned I get a GUID in return that is a GUID for a empty annotation. 

            Annotation setupAnnotation = new Annotation()
            {
                Subject = "Example Annotation",
                FileName = "ExampleAnnotationAttachment.txt",
                DocumentBody = Convert.ToBase64String(new UnicodeEncoding().GetBytes("Sample Annotation Text")),
                MimeType = "text/plain"
            };

            // Create the Annotation object.
            var guid = _orgService.Create(setupAnnotation);

This should be rather simple, but if I use CRM REST Builder to fetch the annotation with that GUID everything is empty:

filesize: null ,
overriddencreatedon: null ,
objecttypecode: null ,
mimetype: null ,
documentbody: null ,
filename: null ,
notetext: null ,

    Hi Lars,

    Try using the code below and see if it works.

                Entity note = new Entity("annotation");
            note["subject"] = subject;
            note["filename"] = filename;
            note["documentbody"] = Convert.ToBase64String(data);
            note["objectid"] = new EntityReference("contact",entityId);
            Guid attachmentId = service.Create(note);

    where

    entityId = Guid / ID of the entity in CRM for which we are retrieving the attachments

    subject = Subject of the note that we are creating

    filename = The name of the file we are attaching to note

    data = the content of the file we are attaching to note

    service= CRM organisation service you are connecting to.

    See: http://www.powerobjects.com/2015/01/21/retrieve-and-create-attachments-associated-to-notes-of-an-entity-in-dynamics-crm/

    Hope this helps.

    Working fine for me. Try fetching your annotation like this:

    http://<ORGURL>/api/data/v8.2/annotations(GUID, NO BRACES)

    Hi Lars,

    The behavior is odd. Normally if there is an exception, the entire transaction is rolled back and the record is not created at all.

    Where are you getting the GUID from? What table are you querying via the REST request?

    If you try to retrieve the same record, via the Organization.svc Service with all columns, do you see any differences?
