    Description

      I am not able to run any app using Wicket 1.5.x including snapshot version.
      I am facing this problem whatever i do. Even running Wicket examples.

      The java code is:

      public class HomePage extends WebPage {

      public void HomePage()

      { final Label label = new Label("test_label", new Model<String>("")); label.setOutputMarkupId(true); add(label); }

      }

      The html code is:

      <html>
      <head>
      <link rel="stylesheet" type="text/css" href="style.css" />
      </head>
      <body>
      <label wicket:id="test_label" />
      </body>
      </html>

      Simple isn't it? But it doesn't work.
      Have found similar problem here: http://apache-wicket.1842946.n4.nabble.com/Menubar-in-wicket-td3758370.html
      But w/o answer.

      Stacktrace:

      Unable to find component with id 'test_label' in [Page class = pl.com.bgk.smx.kgapi.core.web.HomePage, id = 2, render count = 1]
