Hmmm. The new emacs-wiki support for flexible URLs makes this easier.
=) In the old planner one, you needed to make sure your function
returned a non-nil value.

Try this:

;; Add bxid to the list of URL protocols.
(add-to-list 'emacs-wiki-url-protocols '("bxid" planner-bxid-find nil)))

(defvar planner-bxid-path "d:/bram/" "Local bramble root.")
(defvar planner-bxid-extension ".yml" "Extension for YAML-encoded file.")

(defun planner-bxid-resolve (url)
  "Return the file path to URL."
  ;; Remove the bxid://
  (when (string-match "bxid:/?/?" url)
    (setq url (replace-match "" nil t url)))
  ;; Remove the -
  (expand-file-name
   (concat url planner-bxid-extension)
   (concat planner-bxid-path
           (replace-regexp-in-string
            "\\([A-Z0-9]\\)" "\\1/"
            (replace-regexp-in-string "-" "" url)))))

(defun planner-bxid-find (url)
  "If this is a BXID URL, jump to it."
  (find-file (planner-bxid-resolve url)))

You might want to use let instead of setqs for local variables. =)
