Hi, I have a problem related with the pdf index generation with the beamer class. I write a simple lyx document, and when I view it with pdflatex, the resulting pdf leaves the left-side navigation panel empty, even using section and subsection environments in the lyx document. When I export the file to latex to see what happen, I see two strange lines:
that in previous beamer documents had a value of 3 instead of -1000. I don't know why these two numbers are set to -1000, and I also don't know how to reset them to its original value. By setting them to a reasonable value, let's say 3, for instance, the index appears again. Does anyone know how to fix it?
I attach the lyx document.
