Subject: Problem calling Lua during \startsetups

Hello,
I encountered a bit weird thing when I used Lua in \startsetup:
---
\definelayer[T][x=0mm,y=0mm,width=\paperwidth,height=\paperheight]
\directlua{n, m = 1, 11} % Initialization
\startsetups layer
% In my real code (= not in this example)
% the value of 'n' is used here to set the appropriate background,
% = n-th page of a PDF, and also to draw a filled rectangle on
% the left or right side (depending on whether n is even or odd)
% The code bellow fails [1]
\startluacode
print("N=", n)
if n == 2 then
else
end
\stopluacode
\stopsetups
\setupbackgrounds[page][setups=layer,background={T}]
\starttext
% The code bellow works well [2]
\startluacode
print("M=", m)
if m == 2 then
else
end
\stopluacode
\dorecurse{4}{\page[empty]}
\stoptext
---
The problem is that Lua code between \startsetups ... \stopsetups [1] seems to be "parsed" another way than when in [2].
The [1] gives the following error message:
---
! LuaTeX error <main ctx instance>:1: 'then' expected near 'thenelseend'.
---
So it seems like <space>s and/or <\n>s were "ignored".
If you commented [1], the section [2] would work well.
So how to use make Lua work well even between \startsetups ... \stopsetups?
Best regards,
Lukas
