[XeTeX] No (bidi) Arabic with titlesec? & bidi loading settings

[Juan Acevedo]

Thanks Vafa, working like a charm now

For the common good:
commenting out the line

\@ifclassloaded{book}{\@ifpackageloaded{flowfram}{}{\input{book-xetex-bidi.def}}}{}

in xetex-bidi.def

seems to solve (at least some) current conflicts between bidi (via arabxetex) and titlesec, even with a complex titlesec setup and lots of other packages loaded. Using bidi v.1.1.6

May have to do with the redefinitions of \chapter and \section?
