NetBeans won't open FileZilla files

view story

http://askubuntu.com – I installed NetBeans 7.2.1 for Ubuntu 12.0.4. When I connect via FTP to a site and click view/edit a file (FileZilla), NetBeans is opened but without a file in it (it only opens NetBeans without opening the file). Anyone had a similar issue? Could it be permission issue? (HowTos)
