Hi,
when inner/outer alignment of paragraphs is used in a doublesided document with the text direction from RTL, the direction is changed back to LTR starting with the second page.
The reason for this is the \signalinnerrealign (or \signalouterrealign) command.
%\setuppagenumbering[alternative=doublesided] \signalinnerrealign % is used in doublesided documents
\setupalign[inner,righttoleft]
\starttext
\dorecurse{3}{\samplefile{weisman}\page}
\stoptext
