Within a chapter/section scheme, Sometimes I want to be able to have a reference to a section, which would normally appear in the form c.s, where c is the chapter number and s is the section number, to appear just in the form s.
How?
Sample source:
\documentclass[12pt]{memoir}
\usepackage{hyperref}
\usepackage{cleveref}
\crefname{chapter}{Chapter}{Chapters}
\begin{document}
In section \ref{sec:more} of \cref{chap:one} \dots .
And in \cref{sec:one} \dots .
\chapter{One}\label{chap:one}
\section{About one}\label{sec:one}
\section{More about one}\label{sec:more}
\chapter{Two}
In section \ref{sec:more}
\end{document}
Output:
Conflict with creating two tables of contents
The answer that uses zref works as shown in the answer, but when I add code, shown below, to the preamble in order to produce both a long and a short table of contents — with commands \shorttableofcontents and \longtableofcontents just after \begin{document}, I get an error on the line where I use \shorttableofcontents.
The error is:
Undefined control sequence
Here's the entire source, including the extra code for using zref along with the code (courtesy of Christian Hupfer) for creating the two tables of contents.

Trickier answer does work conflict-free
The second, "Trickier" version in the answer does work without conflicting with the code for two tables of contents.
\providecommand{\LastRefSteppedCounter}{}to the preamble preferably before\RegisterPostLabelHook. It was missing inxassoccntv.1.4. I will fix this feature/bug and providexassoccntv.1.5. soon\providecommandby-pass solution is not necessary after that, but can be kept, since it is ignored then.
