Hi Jean-Marc, Could you point me at an example of how this might be done or provide a few lines of code? I'm trying to add a std::list object to OutputParams and getting a wide variety of strange errors. Apparently, including it doesn't like it when I include "InsetFoot.h". I was able to create the list in LaTeX features without trouble, though.
I know very little about how LyX's validate methods work, though. Cheers, Rob
