["Claus Ibsen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/activemq/browse/CAMEL-697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=44190#action_44190 ] 

Claus Ibsen commented on CAMEL-697:
-----------------------------------

The solution is to add this in the TransformProcessor
{code}
    public void process(Exchange exchange) throws Exception {
        Object newBody = expression.evaluate(exchange);
        exchange.getOut().setBody(newBody);

        // propogate headers
        exchange.getOut().getHeaders().putAll(exchange.getIn().getHeaders());
        
        super.process(exchange);
    }
{code}

> transform() doesnt propogate headers

> The new transform() DSL doesn't propogate headers so you can not do:
> {code}
>                 from("direct:four")
>                     .transform().constant("London")
>                     .to("mock:result");
> {code}
> And expect that any headers on the exchange at direct:four is received after the transform
