Exporting does not preserve field order

[kschulst]

When exporting a dataset using CSV, the resulting fields are not ordered in the same way as the original dataset.

Example:

Adresse;Lykketall;Postnr;Type;Skurk;Fødselsdato;Poststed;Id;Navn;charset;contentKey;createdDate;topic;description;contentLength;position;source;tag;contentType;dataset;resourceType;ulid;position;timestamp
