Vars: NSBundle *aBundle, Class aClass, id trayClass

I would consider renaming trayClass to trayInstance (or just tray, or whatever), but that's unimportant from the behaviour POV.

aBundle = [[NSBundle alloc] initWithPath:thePath];

bundleWithPath: might be better. No real harm though, just a possible leak if an exception is triggered before releasing it.

if (aClass = [aBundle principalClass]) {
trayClass = [[aClass alloc] init];

autorelease would be better, for the same reason

[allTrays addObject:trayClass];
[trayview addSubview:[allTrays objectAtIndex:i]];

[allTrays objectAtIndex:i] looks somewhat strange here. Though I dunno the algorithm, so might be perfectly right. Even if wrong, should not cause problems of the kind you observe.

NSLog(@"%@",allTrays);

[trayClass release];

See above.

if (![[allTrays objectAtIndex:i] view]) {
NSLog(@"There is no view");
}
}

[aBundle release];

See above.

When the code goes further....
and I call [window close] (window is an outlet in my maincontroller and there's no equal outlet in the loaded code) PB tells me that the selector [tray window] (tray is the principas class of the external bundle) was not recognized.

Hmmm. Presumed you you actually meant the runtime (PB has nothing to do with that) complained that -[tray *close*] was not recognized, I'd guess the window it gets (auto)released somewhere, and thus next created tray just happens to occupy its place in memory -- getting so the next message sent to "window".

So far as I can say, there seems to be no problem in the loading itself.
