Good thought, permissions are so often the issue, but in this case I think not.

The programmatic effective rights to the field are: READ_VALUE, SET_VALUE, SET_VALUE_ONCE, MODIFY_DEFINITION, DELETE, READ_PERMISSIONS, CHANGE_PERMISSIONS, TAKE_OWNERSHIP and to the entry: BROWSE, READ, WRITE_CONTENT, ADD_PAGE, RENAME, REMOVE_PAGE, FREEZE, ANNOTATE, SEE_THROUGH_REDACTIONS, SEE_ANNOTATIONS, SET_REVIEW_DATE, WRITE_METADATA, CREATE_FOLDER, CREATE_DOCUMENT, SET_EVENT_DATE, CLOSE, DELETE, READ_PERMISSIONS, CHANGE_PERMISSIONS, TAKE_OWNERSHIP.

When I log into the repository through the LF Client with the same ID I can modify all the fields on the entry in question.  Did I miss something?

I appreciate your response.

While I haven't dug through all the details, the essence of my mistake was getting the full FieldValueCollection from the entity, updating one of the fields within it and setting that back onto the entity.  A technique which seems to work is to create a new FieldValueCollection and add the one field to update and it's value to that collection and set that onto the entity e.g.

Entry entry = row.toEntry(); //where the row represents my document
// don't get the existing FieldValueCollection
//FieldValueCollection fvc = entry.getFields();
// create a new one
FieldValueCollection fvc = new FieldValueCollection();
// get the field from the template
Template template = Template.getByName(entry.getTemplate(), session);
Field articleField = template.getFields().get("Article");
// don't set the value as before
//fvc.set("Article", "obstructions and excavations");
// add it
newFvc.add(articleField, "obstructions and excavations");
entry.lock(LockType.EXCLUSIVE);
entry.setFields(fvc);
entry.save();
entry.unlock();

It works.

To deepen my understanding I may try playing with the FieldValueCollection that I derive from the entity to see if I can remove all the fields except the one I want to update, but that's a task for another day.

One other issue that I thought I bumped into.  My impression is that every time I issue

row.toEntry()

I get a brand new entry object, i.e. the values that may have been set with previous setFields methods are not associated with the entry.  I made the mistake of doing things like:

row.toEntry().setFields(fvc);

and did not get what I expected.  Once I created an Entity object and referred to it that problem went away.  The Javadocs seem to jive with that notion.  toEntry() on EntryListingRow says "Returns an Entry derived class instance which represents the entry whose information is contained in this row."

Good morning/afternoon,

I am stuck on this scenario.  I am developing a C# app at this time.  I can insert a document and update its metadata:

            try
            {
                FolderInfo parentFolder = Folder.GetFolderInfo("\\folder", session);
                DocumentInfo document = new DocumentInfo(session);
                document.Create(parentFolder, "myNewDocument - " + DateTime.UtcNow.ToString(), EntryNameOption.None);
               document.SetTemplate("General");
 
               FieldValueCollection fv = new FieldValueCollection();
                fv.Add("Document", "This is the document name");
                fv.Add("Type", "This is the document type");
                fv.Add("Category", "This is the document category");

                document.SetFieldValues(fv);
                document.Save();
            }

When I attempt to update a single value of this existing document - lets say the "Document" value, I can do so but I also wipe out the values for "Type" and "Category".  I tried to follow the suggested approach above, but I get the same results if I update entryInfo or docInfo.  I don't seem to have access to calls which may help me along.  I am using version 9.0 of the SDK.

Template template = Template.getByName(entry.getTemplate(), session);

Field articleField = template.getFields().get("Article");

                EntryInfo entryInfo = Entry.GetEntryInfo(entryId, session);
                if (entryInfo.EntryType == EntryType.Shortcut)
                    entryInfo = Entry.GetEntryInfo(((ShortcutInfo)entryInfo).TargetId, session);

                // Now entry should be the DocumentInfo
                if (entryInfo.EntryType == EntryType.Document)
                {
                    DocumentInfo docInfo = (DocumentInfo)entryInfo;

                    FieldValueCollection fv = new FieldValueCollection();
                    fv.Add("Document", "Document");

                    //docInfo.SetFieldValues(fv);
                    entryInfo.SetFieldValues(fv);
                    entryInfo.Save();

                    //docInfo.Save();
                }
