General ⇒ What control sequence is undefined here?

[Singularity]

When I add \sol{} to the following document, I start to get the error

Undefined control sequence
<argument> \padded@point@block

And the problem is not fixed when I add content to the \sol{<content>}.

The funny thing is, I've used \sol{} in many previous documents without any issues, but I get an error even in the unremarkable MWE below.

What's causing this error and how do I fix it please?

Thanks.

Code: Select all

\documentclass[fleqn,addpoints
,answers
]{exam}
\usepackage{amsfonts,amsmath,amssymb,amsthm,mathtools}
\newcommand{\sol}[1]{\begin{solution} #1 \end{solution}
	\vspace{\stretch{1}}
	\droppoints
}

\begin{document}

\begin{questions}

\question Find the domain, holes all asymptotes (vertical and horizontal) of the function defined in the original document but math mode was removed from here so as to make this document even more minimal and graph it.

\sol{content}

\end{questions}

\end{document}

I found the one single difference between the above nonworking MWE and a working MWE I made: I did not include the "optional" points parameter on the \question command. The following works, but I have no idea why.

Code: Select all

\documentclass[fleqn,addpoints

]{exam}
\usepackage{amsfonts,amsmath,amssymb,amsthm,mathtools}
\newcommand{\sol}[1]{\begin{solution} #1 \end{solution}
        \vspace{\stretch{1}}
        \droppoints
}

\begin{document}

\begin{questions}

\question[1] Find the domain, holes all asymptotes (vertical and horizontal) of the function defined in the original document but math mode was removed from here so as to make this document even more minimal and graph it.

\sol{content}

\end{questions}

\end{document}

It seems omitting the optional points argument works, but not in the case if it's the ver first question. If the first question would have points, the next one without works fine. Seems like a bug.

Here's a quick fix for now, which goes to your document preamble:

Code: Select all

\makeatletter
\let\padded@point@block\relax
\makeatother

If defines the missing command, but just as a dummy command which does nothing.
