Highlighting a NSMenuItem with a custom view?

I have created a simple NSStatusBar with a NSMenu set as the menu. I have also added a few NSMenuItems to this menu, which work fine (including selectors and highlighting) but as soon as I add a custom view (setView:) no highlighting occurs.

CustomMenuItem *menuItem = [[CustomMenuItem alloc] initWithTitle:@"" action:@selector(openPreferences:) keyEquivalent:@""];
[menuItem foo];
[menuItem setTarget:self];
[statusMenu insertItem:menuItem atIndex:0];
[menuItem release];

And my foo method is:

- (void)foo {
  NSView *view = [[NSView alloc] initWithFrame:CGRectMake(5, 10, 100, 20)];
  [self setView:view];
}

If I remove the setView method, it will highlight.

I have searched and searched and cannot find a way of implementing/enabling this.

Edit

I implemented highlight by following the code in this question in my NSView SubClass:

An NSMenuItem's view (instance of an NSView subclass) isn't highlighting on hover

#define menuItem ([self enclosingMenuItem])

- (void) drawRect: (NSRect) rect {
    BOOL isHighlighted = [menuItem isHighlighted];
    if (isHighlighted) {
        [[NSColor selectedMenuItemColor] set];
        [NSBezierPath fillRect:rect];
    } else {
        [super drawRect: rect];
    }
}

If you're adding a view to a menu item, that view has to draw the highlight itself. You don't get that for free, I'm afraid. From the Menu Programming Topics:

A menu item with a view does not draw its title, state, font, or other standard drawing attributes, and assigns drawing responsibility entirely to the view.
