Rich: editor ruins html?

Strange behavior. I am using rich: editor with these attributes: (Excluded data removed)

    HtmlEditor editor = new HtmlEditor();
    editor.setValueExpression("value", ve);
    editor.setTheme("advanced");
    editor.setValueExpression("viewMode", viewModeValueExpression);
            panel.getChildren().add(editor);

      

        
        
        
      

    

Now my problem is that whenever I load a rendered html text like this (in source mode):

<html lang="en" xml:lang="en">
<head>
<title>Done</title>
</head>
<body style="direction: ltr; font-size: medium; color: #0000FF;">
    <p>When the menu loads, navigate to and open Image Editor.</p>
</body>
</html>

      

        
        
        
      

    

Change to VisualMode and then go back to SourceMode, I can see that the editor has deleted all my html data and now the original mode is like this:

<p>When the menu loads, navigate to and open Chul Muzal.</p>

      

        
        
        
      

    

Does anyone know why this is happening?

Thanks!!
