Subject Problem binding multiple params to a bean
Date Thu, 04 Aug 2011 13:00:07 GMT

Hi,

Try as I might I can't bind a value associated with a header onto a bean
reference's second method argument. Null always gets passed to the second
argument on amendTrade(p1,p2). I can log the header value OK, the correct
method gets called but second argument is always null.

I've tried most of the various ways that a bean can be bound to all with the
same effect.

Route:

    from("direct:amend-bond-trade")
      .log("direct:amend-bond-trade")
      .to("log:showBody=false?showBodyType=true&showHeaders=true")
      .log("Header>>>> ${header.previousVersion}")
      .to("bean:radialTransformer?method=amendTrade(${body},
${header.previousVersion})")
     
.to("activemq:queue:nomura.fiet.stp.radial.trades?jmsMessageType=Map");

Log:
