Hi,
I want to implement Singleton design patern for one of my edit parts. So
I make a private final static reference to the edit part, private
constructor and public static getInstance(). The edit part factory calls
getInstance().
The problem is that even when I close the editor and open it again I get
the same singleton instance, although I would expect that every time I
open it, GEF creates a new singleton for me. In other words I want a new
singleton instance in every editing session, and every graphical editor.
What am I doing wrong?
Thanks.
Zeppe

Well, as the name says, a singleton is a singleton (the same static
instance) as long as you do not restart the JRE.
