Well, suspect or not that is what is happening under leiningen2...in all fairness this rarely happens - ususally the errors originate from my code and sometimes for really "complicated" stuff i have big stack traces...this particular example is very straight forward, all the functions have been individually tested and there is practically no nesting (a function calls another and that is it!) - that is why it seems so strange and that is why i resorted here...Believe me very rarely is spend 2-3 hours on an error and incidently it happens mainly when I'm using java interop extensively...

clojure.lang.Numbers.doubles_array takes a Number or ISeq.

The fact that you're not getting precise line numbers for the error in your own source is suspect. How are you compiling and testing your code?

    But it is already a double array, or at least it should be because
    that is what normalize returns...Why start copying into a new array?

    anyway, I tried it and i get this instead:

    ClassCastException [D cannot be cast to java.lang.Number
     clojure.lang.Numbers.double_array (Numbers.java:1068)

    I don't even know where that comes from!!! any ideas?

        You probably want to use double-array rather than doubles. The
        former
        creates an array, the latter is a cast.

            however provide 2

            Thanks a lot for your time btw...

            ps: function.png shows the function thatis being returned
            by make-data when
            passed the key :temporal-window.

                I guess what I'm asking is at which point does the
                array become an
                ArraySeq and why casting it back to a double array
                with 'doubles' doesn't
                work?


            Can you post the whole stack trace?
