Hello members, a happy new year to everybody. And here the problem I have: \setupinteraction[start=state,color=orange] \setupcombinedlist[content][interaction=all] \defineblock[question] \defineblock[answer] \defineenumeration[questions][location=top,coupling=answers] \defineenumeration[answers][location=top,coupling=questions] \hideblocks[question] \hideblocks[answer] \starttext % Problems with the coupling of questions and answers \beginquestion \startquestions Why ConTeXt doesn't work? \stopquestions \endquestion \useblocks[question] \page \beginanswer \startanswers It always give:\crlf sometimes: LuaTeX error and something with lpegmatch?? \stopanswers \endanswer \useblocks[answer] \stoptext This piece of code is compiled with context of TeXLive2011, which is almost every week updated. The piece of compiled into a .pdf file without any problem, but I see no interaction. In other pieces of code, it gives a LuaTex error and something with lpegmatch, but I have no idea about what is spoken. Sometimes I see orange triangles after the enumerations but I have no interaction, the cursor at the screen does not change of form. This if I look at the pdf-file with the acrobat reader. Who of you has any idea howto get interaction between the questions and the answers? The piece of code in one of the manuals of ConTeXt doesn't work with the context I use. It goes about these hidden blocks. There is also given an example with question and answer. It should be nice if it works, Kind Regards, Rene' van Hassel
