Hi Hans,
there is a problem with the command handler and nested \setup… commands.
In the following example the setting for the “two” environment are ignored.
<example>
\defineenumeration[one][text=One]
\defineenumeration[two][text=Two]
\setupenumeration[one,two][alternative=serried,color=red]
\starttext
\startone
First enumeration.
\stopone
\starttwo
Second enumeration.
\stoptwo
\stoptext
</example>
The reason for this behavior is the \setupcounter call in
\everysetupenumeration.
When you look at the internal code for \setupenumeration (mult-aux.mkiv) you
see that the first
element in \setupernumeration (i.e. “one”) is processed with
\mult_interfaces_with_comma_list_element,
at the end of this macro \everysetupenumeration. At this point \setupcounter is
used which
redefines \mult_interfaces_with_comma_list_element. This redefined version is
used for the next
element (i.e. “two”) in \setupenumeration and the values are no passed
(“alternative” and “color”)
to \setupcounter.
