Hi Sven, #+CATEGORY applies to the lines *below* it, independent of outline tree structure. That is why you are getting "Sociology-Article" for your "Emacs installation task: it is the nearest #+CATEGORY line *above* this headline.
#+CATEGORY is only kept for backward compatibility, you probably should not use it for changing the category in the middle of a file, much less in the middle of a complex tree. Properties give much more consistent results. The :CATEGORY: property applies to the entry headline above it, and to the entire tree below it (unless locally overwritten by another property). Everything works fine if I change your example to: * Teaching :PROPERTIES: :CATEGORY: Teaching :END: ** Sanskrit I (WS08) :PROJECT: :PROPERTIES: :CATEGORY: Sanscrit I :END: *** NEXT Look for Introductions :LIBRARY: *** NEXT Borrow the chosen books :LIBRARY: *** NEXT Ask students for convenient date :EMAIL: ** History of Indian Religion (WS08) :PROJECT: :PROPERTIES: :CATEGORY: Indian Religion :END: *** Plan part on Buddhism :MILESTONE: **** NEXT Look for Books :LIBRARY: **** NEXT Chose readings for students :OFFICE: *** Plan part on Hinduism :MILESTONE: **** NEXT Look for books :LIBRARY: **** NEXT Invite guest-speaker :PHONE: * Misc Office :PROPERTIES: :CATEGORY: Misc Office :END: ** Proofread Sociology-Article :PROJECT: :PROPERTIES: :CATEGORY: Misc Office :END: *** NEXT Make a printout :COMPUTER: ** Install Emacs on every colleague's PC :PROJECT: _______________________________________________ Emacs-orgmode mailing list Remember: use `Reply All' to send replies to the list.
