Hello list,

The following example does not compile, complaining “Missing number, treated as zero
needed to see a number, look up 'weird error' in the index to The TeXbook”:

\setuphead           [chapter]
                     [
                      textstyle=cap,
                     ]
\starttext
\startchapter        [title={Oops!}]
\input knuth-gpt \par
\stopchapter
\stoptext

Replacing the textstyle cap by any of bold, slanted, smallcaps, and italic results in a clean compilation but the indicated style is not applied. Using a style description like em, \em, bf, \bf, \sc, does produce the suggested result. The wiki and mail repository are full of examples with the former style names.

Using style=cap (which would change the number as well) also results in a failed compilation, while using style=bolditalic works as it should.
