Witam mam problem mam napisać na zaliczenie aplikację "desktopową" ale mam mały problem. Otóż mam już pomysł na aplikację ale coś nie działa i nie jest w stanie powiedzieć dlaczego. Na moje oko wszystko gra ale dla eclipse nie.

Na razie jest jeden guzik na początku ale w zamyśle ma ich być więcej tylko na razie nie potrafię doprowadzić do działania tego jednego to nie ma sensu robić więcej. Aplikacja ma działać tak że wciskam guzik na RootLayout i przechodzę do EmployeeOverview(do tej pory działa) potem jak kliknę new to otwiera się EmployeeEditDialog i można dodawać dane ale już to n ie działa a ja nie mam pojęcia dlaczego.
Pomocy muszę to zrobić do środy. Tylko bładam bez komentarzy w stylu "tu cos robisz nie optymalnie" albo "to można zrobić lepiej" zależy mi tylko na ty żeby to działało.
