Hey there,
please consider:
\starttext
\defineenumeration[definition][text=Definition, alternative=serried]
\setupnumber[definition][way=bysection, numbersection=yes]
\section{My section 1}
\startdefinition
My fist definition
\stopdefinition
\section{My section 2}
\startdefinition
My second definition
\stopdefinition
\stoptext
It should number my definitions 1.1 and 2.1, but it doesn't. The prefix is
missing.
Any ideas?
Thank you and best regards,
Johann
