No detallar en un moderncv /cventry modificado

No detallar en un moderncv /cventry modificado

Recibo este error al intentar itemizerenovar \cventryen moderncv:

Use of \@@array doesn't match its definition. \end{itemize}}

Mi modificado cventryse ve así:

\renewcommand*{\cventry}[7][.25em]{
    \begin{tabular}{@{}>{\raggedleft}p{.2\textwidth-\tabcolsep}p{.8\textwidth-\tabcolsep}@{}}%
        {\bfseries #2} & {\bfseries #3} \\%
        {\itshape #5} & {\itshape #4}\\%
        \ifthenelse{\equal{#7}{}}%
        {\end{tabular}}%
    {{} & {#7}\\\end{tabular}}%
\par\addvspace{#1}}

Esto es lo que quiero hacer:

\cventry{2016--2019}{Did this and that, including these tasks:%
    \begin{itemize}%
        \item 1;
        \item 2, with sub-items:
        \begin{itemize}%
            \item Sub-item (a)
            \item Sub-item (b)
        \end{itemize}
        \item item 3.
\end{itemize}}
}

Hago llamadas \usepackage{array}.

Probé las alternativas propuestas por @gonzalo-medina en este post:Listas con viñetas en moderncv cventry.

No me funcionaron. Sigo recibiendo el mismo error. ¿Quizás esto suceda porque estoy usando una versión modificada de \cventry?

Lo estoy ejecutando en el último moderncvpaquete disponible en suRepositorio CTAN aquí.

Creo que hay un malentendido y una línea de código incorrecta, pero hagámoslo paso a paso:

1. Malentendido

La definición estándar de comando \cventryes

\renewcommand*{\cventry}[7][.25em]{%
  \cvitem[#1]{#2}{%
    {\bfseries#3}%
    \ifthenelse{\equal{#4}{}}{}{, {\slshape#4}}%
    \ifthenelse{\equal{#5}{}}{}{, #5}%
    \ifthenelse{\equal{#6}{}}{}{, #6}%
    .\strut%
    \ifx&#7&%
    \else{\newline{}\begin{minipage}[t]{\linewidth}\small#7\end{minipage}}\fi}}

Sólo para el último parámetro ( #7) se utiliza una minipágina, que le permite utilizar itemizeetc.

Entonces, para el comando usado, cventrydebe finalizar el tabular e imprimir luego dentro de un argumento de minipágina 7 ( #7):

\newcommand*{\mycventry}[7][.25em]{
\begin{tabular}{@{}>{\raggedleft}p{.2\textwidth-\tabcolsep}p{.8\textwidth-\tabcolsep}@{}}%
    {\bfseries #2} & {\bfseries #3} \\%
    {\itshape #5} & {\itshape #4}\\%
    \end{tabular} % <===================================================
    \ifx&#7&%%
    \else{\newline{}\begin{minipage}[t]{\linewidth}\small#7\end{minipage}}% else <=============
    \fi
\par\addvspace{#1}}

2. Error de código

Su código usado dentro de su comando\cventy

\ifthenelse{\equal{#7}{}}%
{\end{tabular}}%

devuelve un error, use en su lugar

\ifx&#7&%%
        \else{\newline{}\begin{minipage}[t]{\linewidth}\small#7\end{minipage}}% else <=============
        \fi

Mostré el código corregido aquí.

Entonces, con el siguiente MWE (vea que definí un nuevo comando \mycventrypara poder mostrar la diferencia entre el código \cventryde clase original moderncvy el nuevo comando definido \mycventrycon su tabla y lista(s) insertada(s)):

\documentclass[11pt,a4paper,sans]{moderncv}   
\moderncvstyle{banking}          
\moderncvcolor{blue}
