I already told you on IRC, that's possible.

links in the TOC can be named links that means you don't get a LinkDest but a 
name (when using getNamedDest()) that you have to pass to PDFDof::findDest() 
to get the real LinkDest.

It is also possible that a link from the TOC is not a actionGoTo but a 
actionGoToR in that case, in addition to the above things, it means that 
clicking on the link of the TOC has to open the file specified in 
LinkGoToR::getFileName()
