-------------------------------------------------------------

thanks for your fast reply.
yes,i know for this code,it is worked:
--------
		from("timer:myTimer1?repeatCount=1").routeId("route1")
				.errorHandler(deadLetterChannel("direct:a"))
				.process(new org.apache.camel.Processor() {
					public void process(org.apache.camel.Exchange exchange)
							throws Exception {
						throw new Exception("errorA");
					}

				}).id("cProcessor_1");
-------
you mean when i want to let one error handler to controle one route,should code like this?
but i want to know if errorhandler can put before the route when i want it to controle one
route?like the code as in bug description.
i can not let one error handler to controle one route by code "errorHandler.from"?
