Hi! I use org-mode quite a lot of most things and also have a number of "workflows" in my setup, use columnview quite a lot, and also have the habit of entering whatever text I need to write to resolve an issue under the item in org-mode format (quite convenient, then I can just export the subtree and send it as mail).
I have frequently run up against the issue that when trying to generate a column view for a file, it aborts with a strange error. Since this has become more frequent lately, I decided to resolve it. It turns out that if you have something that looks like this: * Top level ** TODO something *** Proposal Blabla *** Submitted Some more blaha. and you have "SUBMITTED" as one of your todo keywords, this line will be interpreted as an item with a keyword but no headline. Since a lot of code assumes that there is always a headline, many functions can get a "nil" as a headline, failing miserably. I solved this issue by requiring that there should always be a headline text (this is after all an assumption made in the code) and rewrote the org-complex-heading-regexp accordingly. Patch is attached. Just my few cents, Mats Kindahl -- Senior Principal Software Developer Oracle, MySQL Department

Since org-column-compact-links only accept a headline text (and not nil), this causes problems with called from org-columns-cleanup-item. This occurs if a 'columnview' dynamic block is used to capture a column view. This patch solves the problem by re-writing the org-complex-heading-regexp to require a headline text instead of allowing it to be optional. This means that items containing only a single word that also happens to be a todo keyword is interpreted as a headline with no todo keyword and just a headline text. --- lisp/org.el | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lisp/org.el b/lisp/org.el index fef7597..e990f49 100644 --- a/lisp/org.el +++ b/lisp/org.el @@ -4824,7 +4824,7 @@ but the stars and the body are.")
