Bonjour à tous,
I'm using amsl module, but it seems there is a probleme
with the startarray/stoparray environment which apear with the "t"
type of column (t for text).
So the basic cases commande doesn't work.
Also the \startcases/stopcases should have the same meaning thas
\cases{xxx} has, but it doen't.
I use textlive distrib with a copy og t-amsl.tex version 2004.11.18
Thank you for any help!

\usemodule[amsl]
\starttext
\startformula
{\bf f(x)} =
\cases{
\sum_{x=1}^n x & if I am false
\\
\displaystyle% just to see the difference
\sum_{x=1}^n x^2 & \text{if I am true}
}
\stopformula
% This formala works as expected, but if I replace
% the forth column of type "l" which contains some \text{xxx} stuffs
% with a column of type "t" without using the \text command,
% there is an error.
\startformula
{\bf e_u(t)} =
\left\{
\startarray{dlll}% ou bien : \startarray{| d | l | r | l}
\displaystyle
\sum_{x=1}^n f(x)
& = ax^2 + b.x + c,
& = a
& \text{Here some text}
\\
\hfil y_2 % just to center stuff within a "d" column
& = 3ax^3 + 3ax^2 + b.x + c,
& = b
&
\\
\sum_{x=1}^n h(x)
& = y_2,
& = a + b
& \text{encore du $(x^2)$ texte}
\stoparray
\right.

\startformula
