There is one problem after another... The line I've mentioned earlier https://github.com/sagemath/sagecell/blob/master/js/session.js#L327 saves and shows the default R plots whose names start with Rplot. This causes read only permissions on files via https://github.com/sagemath/sagecell/blob/master/backend_cell.py#L65 so when R tries to create a new plotting device with the same name it fails. I don't recall reasons for read only but I am pretty sure that's how Volker's display backend system is supposed to function. I have tried to make the file writeable, in which case errors go away, but the same plot gets displayed again and again because it has the same name. Recently user files were prevented from caching, but it does not help here - displaying the same image on the same page does not generate a network request at all, rather the old copy is shown again.
Any ideas on how to fix it? Or how to describe the situation for a search engine? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
