Hi I have a strange error when tangling. I have a large org file with several code blocks tangling in about 20 R files and one bash file. Usually tangling works perfectly, but sometimes one code block does not tangle a code block to a file. These are different blocks. When I change the name of the fiole to be tangled to, it works again. After d=some time, I can rename it again and it works again. The last time it happened, I was debugging the function. But even when deleting all the content of the code block, the problem persists. This persists over restarts of org. The code block looks as follow: ,---- | *** dispProb2D (./R/dispProd2D.R) | :PROPERTIES: | :tangle: ./R/dispProd2D.R | :comments: yes | :no-expand: TRUE | :END: | #+begin_src R | cat(5) | #+end_src `---- In the original version, there is obviously code in it, but the error occurs even in the empty block. I just renamed the block, and it is working again. Any idea what is causing this? Please find the backtrace below. Cheers, Rainer ,---- | ebugger entered--Lisp error: (wrong-type-argument stringp nil) | set-buffer(nil) | (save-current-buffer (set-buffer (get-file-buffer file)) (revert-buffer t t t)) | org-babel-find-file-noselect-refresh("./R/dispProd2D.R") | (let* ((temp-path file) (visited-p (get-file-buffer temp-path)) temp-result temp-file) (org-babel-find-file-noselect-refresh temp-path) (setq temp-file (get-file-buffer temp-path)) (save-current-buffer (set-buffer temp-file) (setq temp-result (progn (run-hooks (quote org-babel-post-tangle-hook))))) (if visited-p nil (kill-buffer temp-file)) temp-result) | (lambda (file) (let* ((temp-path file) (visited-p (get-file-buffer temp-path)) temp-result temp-file) (org-babel-find-file-noselect-refresh temp-path) (setq temp-file (get-file-buffer temp-path)) (save-current-buffer (set-buffer temp-file) (setq temp-result (progn (run-hooks (quote org-babel-post-tangle-hook))))) (if visited-p nil (kill-buffer temp-file)) temp-result))("./R/dispProd2D.R") | mapc((lambda (file) (let* ((temp-path file) (visited-p (get-file-buffer temp-path)) temp-result temp-file) (org-babel-find-file-noselect-refresh temp-path) (setq temp-file (get-file-buffer temp-path)) (save-current-buffer (set-buffer temp-file) (setq temp-result (progn (run-hooks (quote org-babel-post-tangle-hook))))) (if visited-p nil (kill-buffer temp-file)) temp-result)) ("postTangleScript.sh" "./.gitignore" "./DESCRIPTION" "./.Rbuildignore" "./R/parmsFire.R" "./R/parmsPinus.R" "./R/parmsAcacia.R" "./R/parmsRubus.R" "./R/parmsBudget.R" "./R/parameter.R" "./R/endYear.R" "./R/germEst.R" "./R/seedDispersal.R" "./R/seedProduction.R" "./R/fireAliens.R" "./R/clearAliens.R" "./R/prioritisation.R" "./R/beginYear.R" "./R/main.R" "./R/cumulativeDc.R" "./R/dcToIndLayer.R" "./R/competition.R" "./R/dispProd2D.R" "./R/initfun.R" "./R/newInDrak.R" "./R/resetOptions.R" "./R/stats.R" "./R/layerIO.R" "./R/layerNames.R" "./R/onLoad.R" "./NAMESPACE" "./R/package.R")) | (progn (mapc (function (lambda (file) (let* ((temp-path file) (visited-p (get-file-buffer temp-path)) temp-result temp-file) (org-babel-find-file-noselect-refresh temp-path) (setq temp-file (get-file-buffer temp-path)) (save-current-buffer (set-buffer temp-file) (setq temp-result (progn ...)))
