[NTG-context] PDF Keywords in current beta

Hello, in the current beta the usage of the Keyword argument in the \setupinteraction command causes lua to fail in line 136 of lpdf-mis.lua: <code snippet> local keywords = specification.keywords or "" if keywords ~= "" then keywords = string.gsub("[%s,]+", " ") lpdf.addtoinfo("Keywords",pdfunicode(keywords)) end <error> ! LuaTeX error ...text/tex/texmf-context/tex/context/base/lpdf-mis.lua:136: bad argument #3 to 'gsub' (string/function/table expected) </error> I don't know what is expected there since I don't know the PDF specs, but I guess it's easily fixable ;-) Best Regards, Andreas.
