Hi, I use this page to support my question regarding context and summarize the result. Once a problem is solved I will move that text into the "normal" wiki pages.

# Bug: Formula numbering - subnumbers and list of formulas

All following example have following frame:

\usemodule[newmath]

\setupformulas[way=bytext,prefix=no]
\setupsubformulas[conversion=romannumerals]

\starttext
...(example placed here)...
\stoptext


## What works

### formula

Expected formular number: (1)

\placenamedformula[one]{Der einfache Test}
\startformula
c^2 = a^2 + b^2.
\stopformula


Result: (1) -> Works

### align - formular [+]

Expected formular numbers: (1) and (2)

\placeformula
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[+]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[+]
\stopalign
\stopformula


Result: (1) and (2) -> Works

### eqalignno - formula

Taken from wiki and removed the subformulanumber. Expected formular numbers: (1), (2), (3) and (4):

\placeformula
\startformula
\eqalignno{
c^2 &= a^2 + b^2  &\formulanumber \cr
c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\formulanumber\cr
a^2 + b^2 &= c^2  &\formulanumber \cr
d^2 &= e^2        &\formulanumber \cr}
\stopformula


Result: (1), (2), (3) and (4) -> Works

## What does not work

### List of formulas

\placelist[formula][criterium=all,alternative=c]


The list of formulas seems to be totally out of order. Strange numbering and missing names. Needs more investigation once some of the named formulas constructions are fixed.

### subformula

Expected formular numbers: (1a) and (1b)

\startsubformulas[eq:1]
\placeformula[eq:first]
\startformula
PM \xrightarrow R_{PM} \xrightarrow PM
\stopformula

\placeformula[eq:second]
\startformula
R_{PM} = \{ K, F, Z, U, I, J\}
\stopformula
\stopsubformulas


Result: (1a) and nothing -> Does not work.

### align - formula (subformulas->formulas->formula)

Expected formular numbers: (1a) and (1a) and a reference to formular (1b)

\startsubformulas
\startformulas
\placeformula
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[+]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[a]
\stopalign
\stopformula
\stopformulas
\stopsubformulas


Result: nothing and nothing -> Does not work.

### align - subformula

Expected formular numbers: (1.1), (1.2) and (1.c) plus reference on (1.1) and (1.2)

\placesubformula
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[gleichung1a][.1]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[gleichung1b][.2]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[+][c]
\stopalign
\stopformula


Result: (1), (2) and (3) -> Does not work.

Expected formular numbers: (1a) and (1b) plus reference on (1a) and (1b)

\placesubformula
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[gleichung1a][+]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[gleichung1b][]
\stopalign
\stopformula


Result: (1) and (2) -> Does not work.

### eqalignno - subformula

Directly taken form wiki. Expected formular numbers (1), (1a), (1b) and (2):

\placeformula
\startformula
\eqalignno{
c^2 &= a^2 + b^2  &\formulanumber{a} \cr
c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\subformulanumber{b}\cr
a^2 + b^2 &= c^2  &\subformulanumber{c} \cr
d^2 &= e^2        &\formulanumber\cr}
\stopformula


Result: Does not compile Does as the command type{subformularnumber} is unknown -> Does not work.
