Clearly I am now getting myself quite confused where headers are concerned, and have sought as much info as I can on the wiki, but am not getting the desired results. We are talking about ConTeXt MkIV and a doublesided document.
If I only use \chapter throughout and have my setup as:
\setupheadertexts
[{\hfill\getmarking[chapter]\hfill}][]
[{\hfill\documentvariable{metadata:title}\hfill}][]
then everything works as it should: Chapter title as header on recto pages and book title as header on verso pages. And as chapters change so does the header on the recto page.
But this book has some 'chapters' that need to be unnumbered, for which I am using \title in the main body (as well as in frontmatter). Everything else about this choice works, except for the recto headers.
If I use ONLY the setup above, then fairly obviously the numbered Chapters work, but those with \title continue to use the previous Chapter header for the recto pages (the verso pages with the book title is okay). So I understand that I may need to also give a command for the \title 'chapters' to act the way the other numbered chapters do. So I thought I could do this by simply adding the same set of commands above, but this time using title:
\setupheadertexts
[{\hfill\getmarking[chapter]\hfill}][]
[{\hfill\documentvariable{metadata:title}\hfill}][]
\setupheadertexts
[{\hfill\getmarking[title]\hfill}][]
[{\hfill\documentvariable{metadata:title}\hfill}][]
However, when I do this, I get strange behaviour: now the numbered chapters do not show their recto header at all (the verso book title still appears though). The unnumbered \title chapters now show the headers but the same behaviour as indicated above occurs - the next numbered chapter after that carries the previous unnumbered chapter's title.
Obviously I cannot do things the way I am doing it, but I cannot find how to do it.
The other behaviour is the one I noted in an earlier post - if I get \title (used for an introduction) in the frontmatter to work with the correct headers, in the case of this Introduction (which is seven pages), the last of the recto pages does not bear the header 'Introduction'. Perhaps this is expected behaviour?
