Signing a form generated by pdflatex does not show appearance data
If you use pdflatex to generate the form data for the PDF then the "appearance" does not show. For example, if you use the following latex to generate a PDF:
\documentclass{article}
\usepackage{hyperref}
\begin{document}
\begin{Form}
Test
\end{Form}
\end{document}
and then open the resulting document in Okular (test-sign.pdf) and sign it then it will appear blank:

and \end{Form}
, regenerate the PDF, and try to sign that then the appearance data shows up properly:
