The Stepper example on the wiki, http://wiki.contextgarden.net/Stepperfrom which the following snippet comes, \usemodule[pre-60] % use the stepper \setuppapersize[S6][S6] \defineoverlay[invoke] [\overlaybutton{InvokeStepper}] \setupbackgrounds[text] [background=invoke] \setupinteraction[state=start,click=off] \starttext ex nihilo \stoptext fails here with the following error: ! LuaTeX error ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-mis.lua:146: attempt to call upvalue 'pdfaction' (a nil value) stack traceback: ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-mis.lua:146: in function '?' ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-ini.lua:700: in function 'run' ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-ini.lua:722: in function 'finalizepage' [string "\latelua "]:1: in main chunk. Though I am using the latest beta, I do not think this problem caused by changes in the latest release. I have attached the log file for those who are interested. Any suggestions how to rectify this problem would be much appreciated. With kind regards, Michael Guravage
