what do you mean by "object" ?

in Link.h, I see 7 kind of actions (LinkActionKind enum). Maybe they are 
not all implemented.

well, before defining dest, I test the action with :

   if (item->action->getKind () != actionGoTo) *******

the complete code is :

int
epdf_index_item_page_get (Epdf_Document *document, Epdf_Index_Item *item)
{
   if (!item || !item->action || !item->action->isOk ())
     return -1;

   if (item->action->getKind () != actionGoTo)
     return -1;

   LinkDest *dest = ((LinkGoTo *)item->action)->getDest ();

   if (!dest || !dest->isOk ())
     return -1;

   if (dest->isPageRef ())
     return document->pdfdoc->findPage (dest->getPageRef ().num, 
dest->getPageRef ().gen) - 1;

   return dest->getPageNum () - 1;
}
