      Description

      I've got a route that takes an HTTP form post, does some transformations, and sends an email. One of the transforms I'd like to do is to set a header value based on the result of a Groovy expression. I found that setting a header with <groovy>...</groovy> clears out the entire exchange. Setting a header using <constant>...</constant> works fine.

      Here's a route that I'm using to diagnose this problem:

      <camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
      <route>
      <from uri="jetty:http://0.0.0.0:8103/" />
      <to uri="log:from jetty?showAll=true" />
      <to uri="seda:transform" />
      </route>
      <route>
      <from uri="timer:mytimer?period=30000"/>
      <setHeader headerName="application">
      <constant>TEST</constant>
      </setHeader>
      <to uri="log:from timer?showAll=true" />
      <to uri="seda:transform"/>
      </route>
      <route>
      <from uri="seda:transform" />
      <setHeader headerName="fromGroovy">
      <groovy>"my header is $

      {in.headers.application}

      "</groovy>
      </setHeader>
      <to uri="log:after set header?showAll=true" />
      </route>
      </camelContext>

      Messages that originate from the timer look fine:

      12:31:49,332 | INFO | mer?period=30000 | from timer | rg.apache.camel.processor.Logger 88 | Exchange[Id:ID-iago.local/53297-1257192385112/0-16, Properties:

      , Headers:

      {application=TEST, firedTime=Mon Nov 02 12:31:49 PST 2009}

      , BodyType:null, Body:null, Out: null]

      , Headers:

      {application=TEST, fromGroovy=my header is TEST, firedTime=Mon Nov 02 12:31:49 PST 2009}

      , BodyType:null, Body:null, Out: null]

      Messages that originate in response to a request to http://localhost:8103/?application=TEST appear to be lost after the header is set with the <groovy> tag:

      12:32:03,607 | INFO | 34102763@qtp13-1 | from jetty | rg.apache.camel.processor.Logger 88 | Exchange[Id:ID-iago.local/53297-1257192385112/0-18, Properties:{}, Headers:

      , BodyType:org.apache.camel.converter.stream.StreamCacheConverter.InputStreamCache, Body:, Out: null]

      The message after the <setHeader><groovy> is completely blank. I've tried building the route with the Java DSL but it does the same thing. Anything added after the <setHeader><groovy>... element is added to the message, but all previous contents were lost.
