pdfcomment is not working properly with makeidx package

[Former user]

basically, I created a StackExchange question here http://tex.stackexchange.com/questions/161140/makeidx-and-pdfcomment-packages-are-not-working-together the point is that if I use both makeidx and pdfcomment packages simultaneously, highlighted comments do not work at all. you may run in MiKTeX:

\documentclass[a4paper,12pt,oneside,titlepage]{report}
\usepackage[x11names,table]{xcolor}
\usepackage{makeidx}
\usepackage{pdfcomment}

\makeindex

\begin{document}

    \pdfmarkupcomment[author={Oleksandr},subject={test},color=green!25]{I will}{or, maybe not} put here some text, formulas, tables, comments, and some other things.
    Here comes a \index{formula} formula.

    \clearpage
    \phantomsection
    \addcontentsline{toc}{chapter}{Index}
    \printindex

\end{document}

and see that no comments are added. if you remove makeidx related stuff, the comments work fine, as they should. is it possible to fix somehow?

It's a bug in soulpos.sty - see also Issue 13

Same problem without using pdfcomment

\documentclass{report}
\usepackage{soulpos}
\usepackage[rgb]{xcolor}
\ulposdef{\ulflag}{%
\mbox{%
\color{red}\rule[-.85ex]{.25\ulwidth}{1.5pt}%
\color{yellow}\rule[-.85ex]{.5\ulwidth}{1.5pt}%
\color{red}\rule[-.85ex]{.25\ulwidth}{1.5pt}}}
\begin{document}
\ulflag{TestTestTest}
\clearpage
\end{document}

Please file a bug report to Javier Bezos - the maintainer of soulpos - on his homepage and include the links to Issues 13 and 15 here and two StackExchange questions. I already did but didn't get a reply. Maybe you have more luck!
