Go to declaration ends up in offline symbol table

Hi all,

When I am using a "Navigate to declaration" function (CRTL + B or CTRL + Click) on some class method, it takes me to offline symbol table declaration (with no body defined), while I am expecting to end up in actual source file to see the full implementation of that method. I've worked with several Idea projects so far and never had this issue before. Does it have something to do with project structure? Do you know if it's possible to change the path of the declaration to which IntelliJ redirects me? Have you experienced such behavior yourself? It's quite annoying and slows down the work... So any hints are warmly welcome :)

Thanks!

Konrad
