Set the layer content after \starttext or load a font before you set it,4. Februar 2016 um 19:43
But I get two test2 on page 2:
\definelayer[test1][x=.5\paperwidth, y=.5\paperheight, state=start]
\setlayer[test1]{page1}
Remove "state=continue".\definelayer[test2][x=.5\paperwidth, y=.5\paperheight, state=continue]
You have to include a check for the first page, possible are\startsetups[testlayer]
\setlayer[test2]{page2}
\stopsetups
