Hello!
I'm trying to place dynamic content on a layer and now it turns out
that while getting a different pic every time is easy, getting the
layers redrawn wasn't that simple. The wiki has this code:
\definelayer
[pagenumber]
[width=\paperwidth,
height=\paperheight,
preset=middle,
state=repeat]
\setlayer[pagenumber]{Page \pagenumber}
\setupbackgrounds[page][background=pagenumber]
\starttext
\dorecurse{4}{\page[empty]}
\stoptext
AFAIK, that should be a complete minimal sample. Unfortunately it
doesn't seem to work, at least my ConTeXt MkIV of February 8 only
gives "Page 1" on every one of those 4 pages...
How to fix this? Preferably on the "Dummies" level, I'd prefer not to
see the bowels of my ConTeXt, if I can avoid it.
Thanks,
Mari

going on on
http://wiki.contextgarden.net/Layers
you see
\definelayer
[pagenumber]
[width=\paperwidth,
height=\paperheight,
preset=middle]
\startsetups layer
\setlayer[pagenumber]{Page \pagenumber}
\stopsetups
\setupbackgrounds[page][setups=layer,background=pagenumber]
\starttext
\dorecurse{4}{\page[empty]}
\stoptext
Is that what you want ?

Here is a slightly different version which is better when you need more dynamic layers.
\definelayer [pagenumber][width=\overlaywidth,height=\overlayheight,preset=middle]
\defineoverlay[pagenumber][\texsetup{layer}]
\startsetups layer
\setlayer[pagenumber]{Page \pagenumber}
\tightlayer[pagenumber]
\stopsetups
\setupbackgrounds[page][background=pagenumber]
\starttext
\dorecurse{4}{\page[empty]}
\stoptext

This is an example of how it's *not* going to work:
“This is not always what you desire like in the example
above, where on each page the current page number should
be shown and not the number from the first page.”
> How to fix this?
Check out the second one of the two examples of the wiki¹.
It works here.

Doh! Either I can't read or I can't copy.... Sorry for the waste of bandwidth!
The correct example works fine - however, I tried something similar in
my file and it didn't work; but there are so many things that can have
gone wrong as my understanding of layers in ConTeXt is still pretty
shaky. (I understand layers as concept as I've done my share of vector
drawing, I just can't translate that knowledge into ConTeXt, at least
not yet.)
Which is why I needed to backtrack a bit and start from something
simple that works.
I added comments to the examples on the wiki so the next person doing
a careless copy-paste won't fall into the same pit. :-D
Slightly red-eared,
Mari
