Apply \only to environment that contains listing

Question

I cannot find a way to apply \only<n>{content} to a whole itemize environment.

My first approach was:

\only<1>{\begin{itemize}
    \item A
\end{itemize}}

But I get multiple error messages at compile time. I have also tried multiple variations found on the web. But I cannot find a way of hide (not occupying space) the whole list.

EDIT:

Here a minimum non-working example, after reading the comment of @Schrödinger's cat I realized that the problem arises when I use the lstMakeShortInline, in this case, |First|. Without it, it works.

\documentclass{beamer}
\usepackage{listings}
\lstMakeShortInline[language=C,basicstyle=\ttfamily]|
\begin{document}
\begin{frame}[fragile]{Title}
  \begin{columns}[T]
    \column{0.55\textwidth}
    \column{0.45\textwidth}
    \only<1>{
      \begin{itemize}
      \item My code: |First|
      \end{itemize}
    }
    \only<2>{
      \begin{itemize}
      \item Second
      \end{itemize}
    }
  \end{columns}
\end{frame}
\end{document}

Answer 1

Use the onlyenv environment instead of the \only macro:

\documentclass{beamer}
\usepackage{listings}
\lstMakeShortInline[language=C,basicstyle=\ttfamily]|
\begin{document}
\begin{frame}[fragile]{Title}
  \begin{columns}[T]
    \column{0.55\textwidth}
    \column{0.45\textwidth}
    \begin{onlyenv}<1>
      \begin{itemize}
      \item My code: |First|
      \end{itemize}      
    \end{onlyenv}
    \begin{onlyenv}<2>
      \begin{itemize}
      \item Second
      \end{itemize}
    \end{onlyenv}
  \end{columns}
\end{frame}
\end{document}
