Where is my mistake?

I create an test-folder im my home-directory,
copy three raw-files including their xmp-files,
remove one raw-file to get one ophaned xmp-file.

I added ls -l to the script and "rw2" to "candidates"

If I run the script in that folder, the output should show, at the end, 
the orphaned xmp-file but I get only the list of all five files and 
still the error message below.
The error points to  one "(" too many or too few in the line with the 
candidates comparisons.

ls -l

shopt -s nullglob extglob;

# Get all sidecar files
for file in *.{xmp,pts,pp3}
do
   # Generate all permutations of filenames that it may belong to,
   # and let globbing delete the ones that don't exist
   candidates=("${file%.*}"@() "${file%.*}".{nef,raf,orf,rw2}@());

   # If none exist, the file can be deleted
   [[ ${#candidates[@]} -eq 0 ]] && echo rm "$file"
done
