Force pagebreak behind hline in longtable

Question

I try to force the pagebreaks only behind \hline and not behind a \hhline{|~|----}

The first MWE shows the wrong behavior

\documentclass[fontsize=12pt,twoside=false]{scrbook}
\usepackage[ngerman]{babel}
\usepackage{hhline}
\usepackage{ltablex}
\usepackage[table]{xcolor}
\usepackage{blindtext} % Just for the MWE

\begin{document}
\blindtext
\blindtext
\blindtext
\blindtext\\
TEXT\\
\begin{tabularx}{\textwidth}{|p{24mm}|p{19.5mm}|p{28.5mm}|p{19mm}|>{\arraybackslash}X|}
\hline
\rowcolor{gray} Test\newline Test\newline Test & Test\newline Test & Test\newline Test\newline Test & Test\newline Test & Test\\
\hline
\endhead
Test & Test & Test & Test & Test\\\hhline{|~|----}
& Test\newline Test & Test & Test\newline Test & Test\\
\hline
Test & Test & Test\newline Test & Test & Test\\\hhline{|~|----} 
& Test\newline Test & Test & Test & Test\\
\hline
Test & Test & Test & Test & Test\\\hhline{|~|----} 
& Test\newline Test & Test\newline Test & Test\newline Test & Test\\
\hline
Test & Test & Test & Test\newline Test & Test\\\hhline{|~|----} 
& Test\newline Test & Test\newline Test & Test\newline Test & Test\\
\hline
\end{tabularx}
\end{document}

How to force the right behavior automatically?

You could try using \* where you do not want a page break to happen and \ where a page break would be acceptable. — leandriis, Oct 04 '19 at 05:16
What is the purpose of >{\arraybackslash}X, why not simply use X? — leandriis, Oct 04 '19 at 05:24
@leandriis How can I realize your first comment? I get errors if I leave out \\ before \hhline{|~|----} The use of >{\arraybackslash}X is needed in my document but doesn't matter in this MWE. — PascalS, Oct 04 '19 at 05:54
Unfortunately, using \\*\hhline{|~|----} does not seem to work. However, you could switch to \cline{2-5} and use the workaround presented here: https://tex.stackexchange.com/a/52101/134144 — leandriis, Oct 05 '19 at 12:05

In the following solution with tabularray package , we define a unbreakable \myhline:

\documentclass[fontsize=12pt,twoside=false]{scrbook}
\usepackage{blindtext} % Just for the MWE
\usepackage{xcolor}
\usepackage{tabularray}
\SetTblrTemplate{head,foot}{empty}
\NewTableCommand{\myhline}{\cline{2-5}\nopagebreak}
\begin{document}
\blindtext
\blindtext
\blindtext
\begin{longtblr}[
  caption = {Long Title},
]{
  colspec = {|p{24mm}|p{19.5mm}|p{28.5mm}|p{19mm}|X|},
  row{1} = {gray8},
  rowhead = 1,
}
\hline
  Test\newline Test\newline Test & Test\newline Test & Test\newline Test\newline Test & Test\newline Test & Test\
\hline
  Test & Test & Test & Test & Test\
\myhline
       & Test\newline Test & Test & Test\newline Test & Test\
\hline
  Test & Test & Test\newline Test & Test & Test\
\myhline
       & Test\newline Test & Test & Test & Test\
\hline
  Test & Test & Test & Test & Test\
\myhline
       & Test\newline Test & Test\newline Test & Test\newline Test & Test\
\hline
  Test & Test & Test & Test\newline Test & Test\
\myhline
       & Test\newline Test & Test\newline Test & Test\newline Test & Test\
\hline
\end{longtblr}
\end{document}
