Inconsistent behaviour of placefigure[left] for math and text

Inconsistent behaviour of placefigure[left] for math and text

[Aditya Mahajan]

Hi,
  When I use \placefigure[left] with some test, the text wraps around 
the figure. But if the paragraph, contains some formula, it does not 
wrap even after the figure is complete. How can I prevent such a 
behaviour.

Example
\startbuffer[figure]
\placefigure
   [left]
   {}{}
\stopbuffer

\startbuffer[test]
\dorecurse{3}{\input knuth}
\stopbuffer

\startbuffer[mathtest]
\dorecurse{3}{
This is a dummy paragraph to support a little bit of math to show the 
trouble
with placefigure
\startformula
   a = b
\stopformula
This is a dummy paragraph to support a little bit of math to show the 
trouble
with placefigure
This is a dummy paragraph to support a little bit of math to show the 
trouble
with placefigure}
\stopbuffer

\starttext
\getbuffer[figure]
\getbuffer[test]

\page

\getbuffer[figure]
\getbuffer[mathtest]


\stoptext

Thanks,
Aditya

add empty lines around the \start\stop pair 

(somehow display does not go well with the parshape (i must discuss this with taco)

btw, can you make three (or more) examples: (yes|nocheck|text) with left/bottom/fallback placement for the testsuits (see other threads)

I tried playing around with the fallback option, but had unexpected 
results. When I give fallback=left (does that make sense?) I get text 
in the right margin!! See example below.

Using the beta, the numbering is correct. What is fallback=left 
supposed to do? I thought that with

\setupfloat[figure][criterium=\marginwidth,fallback=left]

\placefigure[bottom]{1}{\framed[width=.9\marginwidth]{}} \input tufte
\placefigure[bottom]{2}{} \input tufte

the first figure should float to the left, while the second will go to 
the bottom. But both of them float to the bottom. I am completely 
misunderstanding the feature.

left means left of text; you should test with the beta + the patch i 
sent a few mails ago

(the problem is that otherwise the width is set to the hsize (centered))
