Thanks for the hint. Never saw \setupuserpagenumber[] before.

I tried to run an expanded version of the minimal example Wolfgang
provided with the current minimals and it gave the following error:

 ...
 systems         : begin file simple at line 24
 structure       : begin of sectionblock frontpart
 structure       : title @ level 2 : 0.0 -> \headtext {content}
 ! LuaTeX error ...0910/tex/texmf-context/tex/context/base/strc-pag.lua:104: bad argument #3 to 'format' (string expected, got table)
 stack traceback:
         [C]: in function 'format'
         ...0910/tex/texmf-context/tex/context/base/strc-pag.lua:104: in function 'number'
         ...0910/tex/texmf-context/tex/context/base/strc-pag.lua:172: in function 'prefixpage'
         ...0910/tex/texmf-context/tex/context/base/strc-lst.lua:399: in function 'prefixedpage'
         <main ctx instance>:1: in main chunk.

The example is:

 \definestructureconversionset[frontpart:pagenumber] [] [romannumerals]
 \definestructureconversionset[bodypart:pagenumber]  [] [numbers]
 \definestructureconversionset[appendix:pagenumber]  [] [numbers]
 \definestructureconversionset[backpart:pagenumber]  [] [numbers]

 \startstructureblockenvironment[frontpart]
 \setupuserpagenumber[numberconversion=romannumerals]
 \setuppagenumber[number=1]
 \stopstructureblockenvironment

 \startstructureblockenvironment[bodypart]
   \setupuserpagenumber[numberconversion=numbers]
   \setuppagenumber[number=1]
 \stopstructureblockenvironment

 \startstructureblockenvironment[appendix]
  \setupuserpagenumber[numberconversion=numbers]
 \stopstructureblockenvironment

 \startstructureblockenvironment[backpart]
  \setupuserpagenumber[numberconversion=numbers]
 \stopstructureblockenvironment

 \starttext
 \startfrontmatter
   \completecontent[criterium=all]
   \chapter{Front}
   \input tufte
 \stopfrontmatter
 \startbodymatter
  \chapter{Body}
  \input knuth
 \stopbodymatter
 \startappendices
  \chapter{Appendix}
  \input knuth
 \stopappendices
 \startbackmatter
   \chapter{Back}
   \input knuth
 \stopbackmatter
 \stoptext

The original gave the same error for me. Any help in debugging this
would be appreciated.
