You only get the "WisiPrj Select" menu when you use
wisi-prj-select-cache; you are using -select-parse.

This works, with emacs -Q:

(progn
  (package-initialize)
  (require 'wisi-prj)
  (setq project-find-functions '(wisi-prj-current-parse))
  (wisi-prj-parse-file :prj-file "hello.gpr" :init-prj (ada-prj-default))
  (wisi-prj-select-file "hello.gpr" (ada-prj-default))
  )

You don't need package-initialize if running 'emacs' without -Q.

Note that you don't need (require 'ada-mode); there are auto-loads in
the right places in ada-mode. However, there is not an auto-load on
wisi-prj-parse-file (because you are not supposed to have to do this),
which is why you need (require 'wisi-prj).

I'll see if I can come up with a small fix to make my first suggestion
work.
