I've been searching for solutions and now I can use WebView on modal session using following code. Without using -runMode:beforeDate my WebView cannot process keyboard or mount events:

- (void) OpenURL:(const char *)_url
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    [NSApplication sharedApplication];
    [NSApp setDelegate:self];

    NSString *url = [NSString stringWithUTF8String:_url];

    NSLog(@"OpenURL: %@", url);

    NSRect windowRect = NSMakeRect(10.0f, 10.0f, 800.0f, 600.0f);

    NSWindow *window = [[NSWindow alloc] initWithContentRect:windowRect 
        styleMask:(NSResizableWindowMask|NSClosableWindowMask|NSTitledWindowMask) 
        backing:NSBackingStoreBuffered defer:NO];
    [window setDelegate:self];

    WebView *webview = [[WebView alloc] initWithFrame:windowRect 
        frameName:@"mainFrame" 
        groupName:nil];
    [webview setFrameLoadDelegate:self];
    [[webview mainFrame] 
          loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]]];

    [window setContentView:webview];
    [window makeKeyAndOrderFront:nil];

    // Modal Session

    NSModalSession session = [NSApp beginModalSessionForWindow:window];
    _result = NSModalResponseContinue;

    while (_result == NSModalResponseContinue) {
        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

        _result = [NSApp runModalSession:session];

        // The event loop is a runloop data source, so any ui event will 
        // wake up the source and make this method returns, and so 
        // you can block the run loop and tell him to wait that
        // something append. [2]
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode
                                    beforeDate:[NSDate distantFuture]];

        [self doSomeWork];

        [pool drain];
    }
    [NSApp endModalSession:session];

    [pool release];
}

You need to call [NSApp stopModal], [NSApp abortModal] or [NSApp stopModalWithCode:yourReturnCode] somewhere like this:

- (void)windowWillClose:(NSNotification *)notification
{
    NSLog(@"windowWillClose");
    [NSApp stopModal];
}
