In this function in Component private Object getInstanceToInject(In in, String name, Object bean, boolean enforceRequired) The if condition at the bottom evals to true | if ( result==null && enforceRequired && in.required() ) | { | throw new RequiredException( | "In attribute requires value for component: " + | getAttributeMessage(name) | ); | } | Having said that, it seems theres a small bug in the DebugPageHandler.handle( Exception e ) method as the exception above gets thrown and trapped by this handler but then you get a null pointer on the first call to the conversation context. | conversationContext.set("org.jboss.seam.debug.lastException", e); | As the conversation context isn't created yet. Probably just needs an if null check wrapping round this. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993386#...
