apache camel - Set property on body using bean() -

i'm trying set property called "articleid" on exchange's body , thought explicit way use bean(). however, can't work. when have following in route:

.bean(body(article.class), "setarticleid(${header.articleid})") 

i error message:

caused by: org.apache.camel.component.bean.methodnotfoundexception: method name: setarticleid(${header.articleid}) not found on bean: bodyas[com.example.model.article] of type: org.apache.camel.builder.valuebuilder

my solution has been use processor() , few lines of code in order set articleid property header value, me seems overkill.

i've been complaining on camel-users there isn't way this. here how tackle it:

.setheader("dummy").ognl("request.body.articleid = request.headers.articleid") 

which requires adding camel-ognl dependency.

update

actually, there language endpoint can without setheader, have transform=false or else replaces body result:

.to("language:ognl:request.body.articleid = request.headers.articleid?transform-false")
