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... right, it's ok

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. 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

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 Wolfgang
