formula in itemlist

formula in itemlist

[Hans van der Meer]

I want to place a math formula in the item of an itemlist, but I keep  
getting overfull hboxes.
A minimal  example follows:

\starttext
	\startitemize
	\item dit is een
	\item dit is een formule
	\placeformula[-]
	\startformula
		n= 0		% this is line 7
\stopformula
	\stopitemize
\stoptext

in the log it says:

Overfull \hbox (17.62474pt too wide) in paragraph at lines 7--7
[][]

\hbox(10.41603+4.05064)x0.0
.\glue(\leftskip) 17.62474
.\hbox(0.0+0.0)x0.0
.\hbox(10.41603+4.05064)x0.0
..\rule(10.41603+4.05064)x0.0
..\glue 0.0 plus 1.0fil minus 1.0fil
.\penalty 10000
.\glue(\parfillskip) 0.0 plus 1.0fil
.etc.

Removing the "\placeformula" makes no difference.

Although a fallback to $$ n = 0 $$ makes the overfull hbox go away,  
it does not seem the "ConTeXt" way of doing.
Is this something in formula about not changing a hbox-width inside  
the itemize?

yours sincerely,
dr. H. van der Meer

not so much tested:

\def\setdisplaydimensions
  {\displayindent\leftdisplayskip
   \advance\displayindent\leftdisplaymargin
   \displaywidth\hsize
   \ifdim\hangindent>\zeropoint
     \advance\displayindent\hangindent
   \else
     \advance\displaywidth\hangindent
   \fi
   \advance\displaywidth-\displayindent
   \advance\displaywidth-\rightdisplayskip
   \advance\displaywidth-\rightdisplaymargin
   \hsize\displaywidth}

i'll also add an option to center at the page level and not locally

Will this solve item 60 [1] in the collector?
