[NTG-context] Formula number conversion

[Jean-Philippe Rey]

Hello everybody,

I have a problem with formula numbering in relation with a customized section conversion set. I am using ConTeXt current 

 ConTeXt  ver: 2011.05.18 18:04 MKIV  fmt: 2011.7.31  int: english/english

Here is a minimal example

\definestructureconversionset[CCS][numbers,Character,Romannumerals,numbers,character][numbers]
\setupheads[sectionconversionset=CCS]
\starttext
\chapter{Lorem}
\section{Ipsum}
\placeformula[f1]   % The formula is numbered (1.1) instead of (A.1)
\startformula
a^2 + b^2 = c^2
\stopformula
\section{Dolor}
The famous formula \in[f1] % The reference correctly appears as A.1
\stoptext


I tried different options to \setupformulas but could not get the formula number right. Could someone give me the right setting.

Thanks,
