I have multi files and each file refers to the master file properly and the document can be compiled without problems ....
RefTeX can only refer to the environments , figures, equations, etc when it is stated in the master file ... rather than this C-c ) can't see the other labels in any other file than the master ... kindly advise.
The following are the minimal files
%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
\documentclass{book}
\begin{document}
\chapter{chapter 1 }
\label{cha:chapter-1}
\ref{cha:chapter-1}
\end{document}
and the second file slave.tex
\chapter{Chapter 2 }
\label{cha:chapter-2}
%%% Local Variables:
%%% mode: latex
%%% TeX-master: "master"
%%% End:

Edit 1: Forgot to mention that I import and include the slave into the master file. It is pretty complex on my side as with this minimal file, I am able to reference whatever exists in master only or slave only. On the main document I am building, I am able to reference only whatever is in the master!
Edit 2: The problem was mainly due to using \import to include the files rather than \input.
I noticed also that there is a need to reset RefTex every time I try to add a new file. I will try also to check \cite and whether it is updated in the new scheme. I will also keep using the init.el that you sent... again thanks a lot Jon and I do appreciate this feedback and resolution very much...
user33833 = mosalem2003?init.elfile I included in my answer below: I only included it to show that the answer will even work with your originalinitfile (myinit.elis identical except for all thepredictivestuff, which I don't have on my computer). One other point, if my answer resolved the problem in your opinion, you should click on the checkmark beside the answer to mark it as 'resolved'; you can additionally 'upvote' it if you like, but marking the problem as solved gets this question off the unanswered list.
