title: Detect when users click on links in custom WebKit window
body: <p>In my OSX/Cocoa application, I'd like to detect when users are clicking on a link in my WebKit (WebView) view. I tried setting the UI delegate and implementing "webView:createWebViewWithRequest" however, the request object is ALWAYS nil when this method is called.</p>
  
  <p>The link used is valid. When used with an external web browser it will lead to a valid page.</p>
