Page Layout ⇒ Unwanted multiple ToC Entries for customized Headings

[phitex]

Hello all,

to start each section on the left (even) page, use an Image after the section title and start the contents of the section on the next (right, odd) page, I use the following three commands code in the article class.

Code: Select all

%% cleardoublepage always left (even page):
\makeatletter
\renewcommand*\cleardoublepage{\clearpage\if@twoside
  \ifodd\c@page \hbox{}\newpage\if@twocolumn\hbox{}%
  \newpage\fi\fi\fi} 
\makeatother                                                                              
%% section title always on the left:     
\titleformat{\section}[block]
{\cleardoublepage\huge}
{\thesection} 
{1em{}} 
{ | } %% separate section number from section title using '|'
[{\vspace{8cm}\raisebox{2mm}{\includegraphics[width=14cm]{logos/kamelgrau.pdf}}\thispagestyle{empty\
}\newpage\mbox{}}]%%  any image will do

Everything works fine and looks great in the document, except that the section titles now are printed three or four times in the ToC. How can I get rid of all unnecessary ToC entries?

Any Ideas what I did wrong?

It seems to be caused by the \newpage command in the formatting arguments. Try without, to verify.

For the moment I wrote a minimal Ruby script, which modifies my *.toc file. The \newpage has to cause a new page, but I will give it a try.

thanks.
