IndexFields are always null for vaultApi.Folders.GetFolderDocuments

[kcruzado]

The index fields are not being returned when I retrieve all of the documents.

I tried to retrieve the index fields using the following, but doc.IndexFields returned null…
var documents = vaultApi.Folders.GetFolderDocuments(Folder.Id)
foreach (Document doc in documents)
{
var indexFields = doc.IndexFields;
}

For me to actually retrieve the index fields I am forced to make a second call using the following…
var documents = vaultApi.Folders.GetFolderDocuments(Folder.Id)
foreach (Document doc in documents)
{
var indexFields = vaultApi.Documents.GetDocumentIndexFields(doc.DocumentId);
}

It works, but isn’t ideal.
