Are you sure that this is not a bug in ConTeXt? I normally do not label destinations/references as "name{page:16}".

You can search for page: in spec-fdf.tex, there should be something: \def\fakePDFpagedestination {\iflocation \ifovercomePDFpage \ifarrangingpages \else \bgroup \advance\realpageno \minusone \expanded{\doPDFdestination name {page:\realfolio}}% \egroup \fi \fi \fi} \appendtoksonce \fakePDFpagedestination \to \everyshipout This was added because there was some not upward compatibility handling of page refs in acrobat 5 (simple pag enumber destinations worked ok <5, now it should be object numbers, for which we need some low level support in pdftex).

i believe that the handling of those problems is necessary, but currently your code creates to destinations with the same label. Therefore pdftex gives this warning message. Thus, the reason for this warning/error is IMO a bug and should be fixed.

Sure, but i wonder why it is generated more than once, since it happens at shipout time, are you sure the previous code is in your file?

[if the problem is persistent, in need a minimal example showing it]

it only happens in a project-product structure, so here are the product and its only component: %%-- prod.tex --> % output=pdftex interface=en \startproduct prod \setupinteraction[state=start] %\startbodymatter \component comp \component comp %\stopbodymatter %\startbackmatter \component comp %\stopbackmatter \stopproduct %%-----< %%-- comp.tex --> \startcomponent comp \product prod \chapter{A Chapter} \section{A Section} \input tufte \section{Another Section} \input tufte \stopcomponent %%-----< The files above do not show the error, but if you uncomment the \start|stopbodymatter and/or \start|stopbackmatter then pdftex gives the message about duplicate destinations An additional problem is that i get an empty page at the end of my document. Hope it helps. Best, Jens

It's related to the sectioning structure. (well, it show up there). The problem is in a local manipulation with the real page counter, adding grouping solves the problem: \def\savenofpages {\bgroup \advance\realpageno \minusone \savecurrentvalue\lastpage\realfolio \advance\userpageno \minusone \savecurrentvalue\lastpagenumber\folio \egroup} Now, for that extra last page, this is a side effect of resetting marks (should be an (e)tex primitive, but sofar i could not convince implementers). For the moment i'll add the following to my local cont-new file: \appendtoks \gdef\shipout{\dowithnextbox{\deadcycles\zerocount}}% \to \everylastshipout I hope that there are no unwanted side effects.

Hi Hans, I added the grouping in the file page-num.tex as suggested. The code which you provided for cont-new is also placed. The project I am currently working on works perfectly. The main file contains a series of FLOWcharts and is built with the \startfrontmatter cum suis. So no pdfetex error and no empty page. Thanks for your support! Willi

Hi Hans,

actually, the patch should be:

\appendtoks \ifnum\textlevel>\zerocount \else \gdef\shipout{\dowithnextbox{\deadcycles\zerocount}}% \fi \to \everylastshipout

IMO, patching files here and there by the user is okay for small problems. This problem seems to me a bit more problematic, so, could you please make a bugfix release. Thanks. Jens

However, the first patch works for me witch Context ver: 2002.10.23 and the latter does not!! This one works! \appendtoks \gdef\shipout{\dowithnextbox{\deadcycles\zerocount}}% \to \everylastshipout This one doe not! Hans Hagen wrote:
