\setupheadertexts [\setups{headlist}]
\startsetups [headlist] \framed[align=normal, frame=off] {\placelist [chapter] [alternative=highlight, criterium=all]} \stopsetups
\definelistalternative [highlight] [renderingsetup=list:highlight]
Why does the custom list alternative succeed in a header but fails in a layer? A predefined alternative works perfectly in a layer.
Header and footers are added and calculated after the page is finished but when you put a text in a layer it is fixed at this moment. The problem in your example with the custom list alternative is that you haven’t defined it when it is needed, when you put \definelistalternative and \startsetups … \stopsetups before \setlayer you can see it. For a dynamic layer take a look at this wiki page: http://wiki.contextgarden.net/Layers#Use_dynamic_content Wolfgang
