Sorry, I didn't follow the whole thread (too long), here some Helm
features you may not be aware of:


(helm-comp-read "test: " '(("un" . 1) ("deux" . 2) ("trois" . 3)))
=> 1
(helm-comp-read "test: " '(("un" . 1) ("deux" . 2) ("trois" . 3)) :alistp nil)
=> "un"
(helm-comp-read "test: " '(("un" . 1) ("deux" . 2) ("trois" . 3)) 
:marked-candidates t)
=> (1)
(helm-comp-read "test: " '(("un" . 1) ("deux" . 2) ("trois" . 3)) 
:marked-candidates t :alistp nil)
=> ("un")

Hope that helps.
