Lists and alternative=command

Lists and alternative=command

[Rogers, Michael K]

I'd love help with this:  I have list that uses alternative=command, and it stopped working when I switched from last year's TeXLive context to a recent beta.  I've minimized the problem to this example:

\definelist      [MyList]
\define[3]\MyListEntry{:#1:#2:#3:}
\setuplist       [MyList]     [alternative=command,command=\MyListEntry]
\starttext
\writetolist[MyList]{First}{Second}
\placelist[MyList]
\stoptext

It generates the following error three times, once per argument in \MyListEntry, I suppose.

ConTeXt  ver: 2012.05.14 16:00 MKIV  fmt: 2012.5.16  int: english/english
...
! Argument of \MyListEntry has an extra }.

6     \placelist[MyList]
