This is very strange. All the SHtml stuff works just fine within CometActors (if they didn't CometActors wouldn't work... and they do). If you can create a reproducable example (preferably as a GitHub project), please open a ticket https://liftweb.assembla.com/spaces/liftweb/tickets > However, for some reason if I change the highlighted line of code to > say: > {f.getName} > I get the proper NodeSeq which lists all the files in the directory. > > Seems to me that the SHtml class functions are encountering an error > scenario(frm which its unable to recover).
