;;from the website you linked
(/fields/ [:firstname :first]:last :address.state)
;; you can alias a field using a vector of [field alias]
Your vector argument should look like this:
[[:firstname :first]:last :address.state]
or like this (if you're not aliasing):
[:firstname :last :address.state]
or in your case exactly:
[:id]
[[:id :identity]] ;;with aliasing
is this how your 'fields-vector' looks like?

ps: I've not looked at the source of 'fields', I may be wrong...

Thank you guys for your answer. apply was the first thing I used but I
got the following error:
java.lang.ClassCastException: clojure.lang.Keyword cannot be cast
to clojure.lang.Associative
and i thought i am not going the right way. What i am more
specifically trying to do is this:
http://sqlkorma.com/docs#select
In the link above, the select example takes a (fields ....) function
so, I made the following wrapper because it was convenient to use in
my project:
(defn find-one-row [entity fields-vector where-hash-map]
(first (select entity (apply fields fields-vector) (where
where-hash-map) (limit 1))))
...but it throws the error i mentioned
If i hardcode the fields like this, it works fine:
(defn find-one-row [entity where-hash-map]
(first (select entity (fields :id) (where where-hash-map) (limit
1))))
Any ideas?

you said it yourself in your first post... :) 'apply' is what you're
looking for!
