[Gtk-sharp-list] Multiple Window Objects and Reference Exceptions

[Pablo Fischer]

Hi all!

Well, now I have another problem. I'm working with 3 Objects that are
extended from the Gtk.Window class. 

I can open other window.. and close it, but when I try to reopen it, my
application crashes with the following exception:

Unhandled Exception: System.NullReferenceException: A null value was
found where an object instance was required

I dont know why it's crashing, but let me explain how Im creating the
object:

In the constructor I load the glade file where I have my window, then I
Autoconnect it to my app (just with ui.Autoconnect(this)), then in the
function ShowWindow I just 'copy' the glade widgets to gtk widgets, and
that's all.

Im creating the object with:
    private void ShowAccountsWindow() {
      if(aw == null) {
	aw = new AccountsWindow(this, accounts);
	aw.ShowWindow();
      }

      else {
	aw.ShowWindow();
      }
    }

I've also tried with the IsActive property but too, it fails :(.

Am I missing something?

Thanks!
Pablo
