Weird things...

Hi all...

I would like to report a weird behavior when compiling the attached tex 
file...

If I put the background layer definitions before the columnset 
definitions everything works well.

\useexternalfigure[test][buttons][frame=true]
\definelayer[graphics][x=0.5cm,y=2cm,width=\paperwidth,height=\paperheight]
\setupbackgrounds[page][background=graphics]
\definelayerpreset[lefttop][corner={left,top},location={right,bottom}]
\setlayer[graphics][preset=lefttop]{\externalfigure[test]}

\definecolumnset[threecolumns][n=3,distance=12pt]
\definecolumnsetspan[spantwo][n=2]
\definecolumnsetspan[spanthree][n=3]
\definecolumnsethsize{threecolumns}{1}{1}\OneColumn
\definecolumnsethsize{threecolumns}{1}{2}\TwoColumns
\definecolumnsethsize{threecolumns}{1}{3}\ThreeColumns

If I put them after then I get an "ERROR: Bad character code (648)"

\definecolumnset[threecolumns][n=3,distance=12pt]
\definecolumnsetspan[spantwo][n=2]
\definecolumnsetspan[spanthree][n=3]
\definecolumnsethsize{threecolumns}{1}{1}\OneColumn
\definecolumnsethsize{threecolumns}{1}{2}\TwoColumns
\definecolumnsethsize{threecolumns}{1}{3}\ThreeColumns

\useexternalfigure[test][buttons][frame=true]
\definelayer[graphics][x=0.5cm,y=2cm,width=\paperwidth,height=\paperheight]
\setupbackgrounds[page][background=graphics]
\definelayerpreset[lefttop][corner={left,top},location={right,bottom}]
\setlayer[graphics][preset=lefttop]{\externalfigure[test]}

I have spent one hour trying to figure out what was wrong with my file 
and only by hasard, after having done some experiments, I put the things 
in the "working" order.

Why this happens?

See you,
Fabio

Because an interal ConTeXt macro (\dododosetlayer) is calling
a TeX primitive (\chardef) with a number that is higher than 256.
That number has become so high because of the columnset
definitions, which is why changing the ordering fixed it.

A full fix of the bug requires some work, simply changing that
one \chardef didn't cut it (the 'bad character code' moves
elsewhere).

Cheers,

Taco

ah. that one took me a while .. in page-lyr.tex,

   
\chardef\layerpagebox\csname\@@layerbox#2\currentlayer\layerpage\endcsname
   \chardef\layerbox\csname\@@layerbox#3\endcsname

should be:

   
\mathchardef\layerpagebox\csname\@@layerbox#2\currentlayer\layerpage\endcsname
   \mathchardef\layerbox\csname\@@layerbox#3\endcsname

(column sets need lots of boxes in etex mode and then the layer box ends 
up > 255 and using a chardef here is not working any more)

[you need to remake the format]

it's in the \layerbox and \pagelayerbox ... (speedups and convenience)

(i wonder if i have more of such errors)

another one:

   \mathchardef\collectorbox\csname\@@collectorbox#1\endcsname

two times in core-box
