Hi,


I'm writing an application with glade-2, and my glade file consists of
two widgets: a Gtk.Window window1 and a Gtk.FileSelection
fileselection1.

I have added an 'open' button, where I would like to call the
FileSelector, but when I try to load the FileSelection from the glade
file, I get nothin (null), so when I want to show the fileSelection,I
get this exception:

                                                                                
Unhandled Exception: System.NullReferenceException: A null value was
found where an object instance was required
in <0x0000e> 00 Window.myWindow:OnOuvrir1Activate
(object,System.EventArgs)
in <0x00067> 01 System.MulticastDelegate:invoke_void_object_EventArgs

in <0x000d9> 00 Window.myWindow:.ctor ()
in <0x0002c> 00 Window.myWindow:Main (string[])
 

However, when I construct my FileSelection Dialog without glade, the
dialog shows correctly.

Does anyone here have an idea?
