After customizing my Table of contents as shown below, my toc overflows onto the footer and doesn't go to the next page.
Here is the toc customization I have done :
\titlecontents{chapter}[0em]{\addvspace{15pt}\bfseries}{\fontsize{13}{13}\bfseries\chtocfont\contentslabel{2.5em}}{\hspace{2.5em}}{\hfill\contentspage}
\titlecontents{section}[2.5em]{\addvspace{5pt}\bfseries}{\fontsize{13}{13}\fontseries{bc}\sectocfont\contentslabel{1.25em}}{\hspace{2.5em}}{\hfill\contentspage}
\titlecontents{subsection}[5em]{\addvspace{5pt}\bfseries}{\fontseries{bc}\sectocfont\contentslabel{1.25em}}{\hspace{2.5em}}{\hfill\contentspage}
\titlecontents{subsubsection}[7.5em]{\addvspace{5pt}\bfseries}{\fontseries{bc}\sectocfont\contentslabel{1.25em}}{\hspace{2.5em}}{\hfill\contentspage}
\titlecontents{paragraph}[9.5em]{\addvspace{5pt}\bfseries}{\fontseries{bc}\sectocfont\contentslabel{1.25em}}{\hspace{2.5em}}{\hfill\contentspage}
\chtocfont is for using Helvetica as a font for the chapter content line, \sectocfont for using the Lucidia Grande as font for the content line.
Here is a screen shot of the issue I am having. Note that some entries from the toc are not shown at all.
the follow link contains a paste of a tex example show the problem i have : http://pastebin.tlhiv.org/KZus0jGD

tocloftortitletoc, not both. If I remove\usepackage{tocloft}and the\renewcommand{\cftdot}{...}line, there is no problem.
