Expected or Desired Behavior

Field Customizer can be applied to Name column in Document Library

Observed Behavior

Field Customizer can't be applied to Name column in Document Library

Steps to Reproduce

• Create simple Field Customizer
• try to apply it to the FileLeafRef or LinkFilename field in any document library with CSOM/JSOM/REST:

var ctx = new ClientContext("https://contoso.sharepoint.com");
ctx.Credentials = new SharePointOnlineCredentials(username, password);
var web = ctx.Web;
var docLib = web.Lists.GetByTitle("Documents");
var field = docLib.Fields.GetByInternalNameOrTitle("FileLeafRef");
ctx.Load(field);
ctx.ExecuteQuery();

if (field.ClientSideComponentId != clientSideComponentId)
{
  field.ClientSideComponentId = clientSideComponentId;
  field.Update();
  ctx.ExecuteQuery();
}

• no luck

Note: the customizer is applied if you use debug url to apply it.

@AJIXuMuK - This is by design as the name field is marked as a nocustomize field. If you believe you need the name field to have a field customizer on it please open up a new request in user voice to request this feature.

@mcmynn83 it is so weird!

1. If it is noncustomizable why Column Formatting can be applied and Field Customizer - no?
2. What is so special in it? Why Title column in list is customizable but this one - not?
3. Why the field customizer is applied in debug mode?

Why did you actually decide to do it noncustomizable?

@AJIXuMuK This looks like it might be a duplicate of my issue #906 and it seems like the situation has changed since. I am able to apply a field customizer to a name column without issue now.

@JLRishe do you have some information on how you managed to get this working?

[JLRishe]

@wobba I've replied on issue #906 since your original question is there.

It works for Modifed and DocIcon fields, but not for FileLeafRef.

FileLeafRef works fine in debug mode though.
