Hi. I faced with strange (for me) behavior of combination of '\setupmathematics' and '\iint'. Consider the following example: <example name="ex1.tex"> \setupbodyfont[xits] \setupmathematics[integral=displaylimits] \starttext This is a sample. \startformula \exp^{\imath\phi}=\cos\phi+\imath\sin\phi \stopformula \startformula \int_{a}^{b}f(x)\text{d}x=F(x)+C \stopformula \startformula \iint_{D}f(x,y)\text{d}x\text{d}y=\mu(D),\quad\text{here $\mu$ is a measure} \stopformula \stoptext </example> If I comment line with '\etupmathematics' then I could compile the example without error. The shown example however gives error when compiled by context (mkiv): <error> ! Missing } inserted. <inserted text> } <to be read again> $ \stopdisplaymath ->\stopinnermath $ $\par \afterdisplayspace \par \egroup \dostopformula ...eter \c!alternative \v!formula } \dostoptagged \dostoptagge... l.21 \stopformula ? </error> Does this mean that 1) something wrong with font setup? 2) mathematics setup? P.S. I took fonts (symlink) from TL2010 installed in parallel. --- WBR, Vladimir Lomov
