    Not a function error in SEAM Remoting

      We are trying to integrate SEAM remoting functionality. Thus we exploded SEAM remoting example seam-helloworld. Everything works fine. But if we integrate this example one-to-one in our existing SEAM projekt we get the error Seam.Component.getInstance("helloAction").sayHello is not a function. No debug info, though debug is set true in components.xml.


      Here the generated html page:
