> Methods in Seam 2.1.0.GA that call Renderer.render( ... ) multiple times inside the same method throws an NPE. This works fine when I deploy the app, however in testing I get the NullPointerException. I modified the mail example packaged with Seam 2.1 to call render twice from the MailExample.send method and I get the same thing:
