[Mono-list] Reflection odd exception

[Carlos Ble]

Hi!
Iam working with reflection by loading some clases dinamically. This is
a piece of "pseudo" code:
System.Object[] paramsObj = new System.Object[] {...params...};
Assembly assembly = Assembly.GetExecutingAssembly();
System.Object childWin =       
  AppDomain.CurrentDomain.CreateInstanceAndUnwrap(assembly.FullName,    
  managerClass,true, BindingFlags.Instance|BindingFlags.Public,
  null, paramsObj, null, null, null);

Everything works fine but one of the classes to load has this method:

bool OnWinDeleteEvent (Gdk.Event e) // Instead of (object o, EventArgs
e).
{
  ...
  return true;
}

I can compile all successfull but in runtime, CreateInstanceAndUnwrap
call launchs this exception: 

Exception has been thrown by the target of an invocation.

If I change arguments to (object o, EventArgs e), it works fine. Can
somebody write some comments about this behaviour?.

Thanks
