pagestyle of multipage tableofcontents with scrbook class?

Question

I'm using scrbook class with a frontmatter and mainmatter and I've adjusted the contents of my headings using \usepackage{scrlayer-scrpage}.

Just like I wanted, the first page of the Contents has a plain pagestyle (roman numeral page number at the bottom) But my problem was on the second page of the Contents: It has a Chapter heading at top, and a roman numeral page number at the bottom. \tableofcontents is supposed to generate entirely \pagestyle{plain} type page numbers, even when the contents span two or more pages. Is that correct?

I've fixed it by manually adding \pagestyle{plain}\tableofcontents and then adding \mainmatter\pagestyle{scrheadings} afterwards, to get plain Contents pages on both, and then revert to headers and footers on for the mainmatter chapters (except the first chapter pages which are plain, of course).

So, I just want to know if I've broken something in preamble to cause \tableofcontents to misbehave, or if what I'm experiencing normal behavior of the \tableofcontents?

Answer 1

It is the expected behavior. The first page of the Contents is a chapter page, so it uses pagestyle plain. The second page is "normal" page and uses the current pagestyle, e.g. scrheadings.

To set pagestyle plain for the whole Contents you can use

\AfterTOCHead[toc]{\pagestyle{plain}}
\AfterStartingTOC[toc]{\clearpage}

If this should be done also for all lists controlled by KOMA-Script package tocbasic (like List of Figures or List of Tables), remove the optional argument:

\AfterTOCHead{\pagestyle{plain}}
\AfterStartingTOC{\clearpage}

Example:

\documentclass{scrbook}
\usepackage{scrlayer-scrpage}% sets automatically `\pagestyle{scrheadings}`

\AfterTOCHead{\pagestyle{plain}}
\AfterStartingTOC{\clearpage}

\usepackage{blindtext}% only for dummy text
\begin{document}
\frontmatter
\tableofcontents
\chapter{Introduction}
\Blindtext
\mainmatter
\Blinddocument\Blinddocument
\Blinddocument\Blinddocument
\Blinddocument\Blinddocument
\end{document}
