FCKeditor and Native Javascript

Hello

I'm working on a GWT project and I want to use FCKeditor. In order to have two editors with two differents toolbars on the same page I tried to create an editor in native Javascript.
This is my fonction:

private static native void creer_editeur() /*-{
var editeur = new $wnd.FCKeditor( 'FCKeditor_Basic' );
editeur.Config['ToolbarStartExpanded'] = true ;
editeur.Create();
$wnd.editeur = editeur;
}-*/;

My problem is that I have the text area but not the toolbar and I don't manage to make it appear.
Does anyone have an idea?

Thanks
