This is 'not right' but I suspect it is not all that simple
to fix the context core to do this properly (I would love to be
proved wrong).
This is a serious bug. Even a simple example fails with the same
error.
\starttext
\framed{
\startformula
x^2 = x\cdot x
\stopformula}
\stoptext
A quick workaround is to use frametext instead of framed, but I am
pretty sure that the above example used to work at some stage.

hmm, I can test with two older release.

Hi Aditya,
it is more a problem related to horizontal and vertical modes/boxes, you can
test it by placing \startformula .. \startformula into a hbox/vbox and only
the
vbox solution works.
This is working
\vbox
{\startformula
x^2 = x\cdot x
\stopformula}
This fails
\hbox
{\startformula
x^2 = x\cdot x
\stopformula}
You can use disply math in a frame by setting explivied values for width
and height of the frame.
\framed
[width=5cm,height=4cm]
{\startformula
x^2 = x\cdot x
\stopformula}
This solution works also in combination with a buffer
\startbuffer
\startformula
x^2 = x\cdot x
\stopformula
\stopbuffer
\framed[width=6cm,height=4cm]{\getbuffer}

That was obviously the wrong diagnosis. Just lucky that the patient
didn't die.
Also interesting:
\setuplayout[grid=yes]
\hbox{\startformula x^2 \stopformula}
(I tried that because in grid mode, the \startformula wraps the
body inside a \vbox)
Well done Wolfgang,
Taco
