[NTG-context] Strange error with bookmarks

14 Oct 2014

      It does indeed be somehow connected with the specific reader that
I use (okular). Nevertheless, evince gives the same error, and I have found out,
that even jpdfbookmarks_cli has problems as it raises an exception when I try
to dump the bookmarks:

  Exception in thread "main" java.lang.ClassCastException: com.lowagie.text.pdf.PdfNumber cannot be cast to com.lowagie.text.pdf.PdfString

Still, in Acrobat Readers it works perfectly.

In the meantime I have came up with a ConTeXt solution, so one can compare
the resulting PDF files. Unfortunately I have only a limited understanding
of the details of PDF files.

The file giving the error is:

\pdfcompresslevel=0 \pdfobjcompresslevel=0
\setupinteraction[state=start,focus=standard]
\placebookmarks[part,chapter][part,chapter][number=no]
\starttext
\chapter{0}
\startpart[title={A}]
  \chapter{1}
  \chapter{2}
\stoppart
\startpart[title={B}]
  \chapter{3}
  \chapter{4}
  \chapter{5}
  \chapter{6}
  \chapter{7}
  \chapter{8}
  \chapter{9}
  \chapter{10}
\stoppart
\completecontent[criterium=all]
\stoptext

While the following files gives no problems in the applications that I have
tested (note the last command):

\pdfcompresslevel=0 \pdfobjcompresslevel=0
\setupinteraction[state=start,focus=standard]
\placebookmarks[part,chapter][part,chapter][number=no]
\starttext
\chapter{0}
\startpart[title={A}]
  \chapter{1}
  \chapter{2}
\stoppart
\startpart[title={B}]
  \chapter{3}
  \chapter{4}
  \chapter{5}
  \chapter{6}
  \chapter{7}
  \chapter{8}
  \chapter{9}
  \chapter{10}
\stoppart
\placecontent[criterium=all]
\stoptext

While trying to make a longer document with ConTeXt I stumbled into a
strange error with the latest beta (I spotted it for the first time some
time ago). For the following file:
\setupinteraction[state=start,focus=standard]
\placebookmarks[part,chapter][part,chapter][number=no]
\starttext
\chapter{0}
\startpart[title={A}]
   \chapter{1}
   \chapter{2}
\stoppart
\startpart[title={B}]
   \chapter{3}
   \chapter{4}
   \chapter{5}
   \chapter{6}
   \chapter{7}
   \chapter{8}
   \chapter{9}
   \chapter{10}
\stoppart
\completecontent[criterium=all]
\stoptext
ConTeXt would generate a file in which the link for chapter "6" is not
working. Neither the link in the table of contents works nor the link in
the generated PDF bookmarks. When removing the second line, the link in
the table of contents doesn't work, but everyting is ok if one removes
the table of contents. What seems even more weird for me, the problem
goes away if one removes *any* chapter. It persists for chapter "6" even
if chapters are distributed differently between parts without changing
their order.
Am I doing something wrong? I hope someone might be able to help.
It works here (with summatrapdf) ... can it be a viewer issue? Do you 
run the latest context?
