I've tried to write a custom org-blocker-hook but it doesn't work, unfortunately. Can you (or someone else) tell me please what's wrong with my code? (defun org-block-todo-with-blocked-parent (change-plist) ;; check whether we are in a endless loop: (if (plist-get change-plist :org-block-todo-with-blocked-parent) ;; We are in a endless loop: don't block (return t) t ;; We are not in a endless loop: go to the parent heading (save-excursion (org-back-to-heading t) (ignore-errors (org-up-heading-all 1)) ;; generate a fake change-plist with a flag to indicate a endless loop (setq fake-change-plist (list :type 'todo-state-change :from "DONE" :to "TODO" :position 0 :org-block-todo-with-blocked-parent t)) ;; check whether the parent heading should be blocked and return the result (save-match-data (run-hook-with-args-until-failure 'org-blocker-hook fake-change-plist))))) (add-hook 'org-blocker-hook 'org-block-todo-with-blocked-parent) > I don't expect to change this because it would make the > mechanism a lot more complex and slower. I think it's essential to provide this eventuality. For example this tree: * organize party :PROPERTIES: :ORDERED: t :END: ** TODO send invitations *** TODO send invitation to Paul *** TODO send invitation to Nicole *** ect. ** TODO buy meals and drinks :PROPERTIES: :ORDERED: t :END: *** TODO write shopping list *** TODO get money from my bank account *** TODO buy food *** TODO buy drinks with this tree, only "send invitation to Paul" and "send invitation to Nicole" should be on my agenda. But "write shopping list" is also an my agenda list (although it shouldn't: I can't write a shopping list if I don't know how many people will come to my party). best regards, Daniel > - Carsten > > On Mar 24, 2009, at 8:13 PM, Daniel Hochheimer wrote: > >> Hello, >> >> first of all, please excuse my poorly english. >> >> It seems there is a bug in the handling of simple dependencies. >> I think an example tree is the best solution, to show you the bug: >> >> * Projects >> #+CATEGORY: Projects >> *** TODO foo bar project >> :PROPERTIES: >> :ORDERED: t >> :END: >> ***** TODO foo subproject :FooSubproject: >> ******* TODO Task 1 >> ***** TODO bar subproject :BarSubproject: >> ******* TODO Task 1 >> >> This is in my .emacs file: >> (setq org-enforce-todo-dependencies t) >> (setq org-agenda-dim-blocked-tasks 'invisible) >> (setq org-odd-levels-only t) >> >> the expected global todo agenda view imho is: >> >> Projects: Task 1 :FooSubproject: >> >> but actual it is unfortunately: >> >> Projects: Task 1 :FooSubproject: >> Projects: Task 1 :BarSubproject: >> >> >> Imho "Task 1" from "bar subproject" should not be visible, >> because "bar subproject " is blocked because of the >> ORDERED property (therefore it's childs should be blocked, too) >> >> >> Is it easy / possible to fix this bug?
