Still problem with \eqalign :(

Still problem with \eqalign :(

[Matthias Weber]

After downloading the release from yesterday,
simple \eqalign's seem to work, but I run into problems with


\starttext
\placeformula[-]
\startformula
\eqalign{
c:[-1,1] &\to R^2
\cr
t&\mapsto
\left\{
\eqalign{
-(t^2,0) \qquad&\text{if $t\in[-1,0]$}
\cr
(0,t^2) \qquad&\text{if $t\in[0,1]$}
}
\right.
}
\stopformula

\stoptext

so you have a nested eqalign; before i spend hours on this, maybe taco has an idea (lookahead, preamble, whatever problem?)
