Why is logout button asking for credentials for logging out?

When I click on logout button present in my mashup it always prompts for credentials ,after entering the credentials it logs out.

UI Elements, aka widgets, are pure Javascript /HTML5 code, no Java at all. Well still with the Java ones you can decompile it and recompile it again, I did for CSVParser extension already.
