bug getting part for \setupheadertexts?

[Pablo Rodriguez]

Dear list,

as Hraban already reported, there might be a bug in:

    \setupheadertexts[section][chapter][part][section]

    \starttext
    \dorecurse{10}{\part{Part}
        \chapter{Chapter}
        \dorecurse{5}{\section{Section}\page}}
    \stoptext

Replacing [part] with [\getmarking{part}] gives the following error message:

lua error       > lua error on line 7 in file /home/ousia/a.tex:
...eta/tex/texmf-context/tex/context/base/mkiv/strc-mar.lua:413: attempt

Could you confirm whether this is a bug? (Hraban has already reported it.)

Many thanks for your help,

Pablo

Replying to myself (and to Hraban). This solves the issue:

    \setuphead[part][placehead=yes]
    \setupheadertexts[section][chapter][part][section]

    \starttext
    \dorecurse{10}{\part{Part}
        \chapter{Chapter}
        \dorecurse{5}{\section{Section}\page}}
    \stoptext

From https://mailman.ntg.nl/pipermail/ntg-context/2017/088407.html, the
following line has a wrong invocation:

  \setupheadertexts[][\getmarking{chapter}][\getmarking{part}][]

It should read (I just discovered it):

  \setupheadertexts[][{\getmarking[chapter]}][{\getmarking[part]}][]

I hope it helps Hraban. And sorry for the noise,

Pablo
