Description

I have a routetemplate:

routeTemplate("appendtobody")
  .templateParameter("append")
  .templateParameter("in")
  .templateParameter("out")
.from("{{in}}")
.transform(body().append("{{append}}"))
.to("{{out}}");

 

I create the route from template like this:

<templatedRoutes xmlns="http://camel.apache.org/schema/spring">
   <templatedRoute routeId="100-2" routeTemplateRef="appendtobody">
      <parameter name="append" value="appendvalue"/>
      <parameter name="out" value="file://C/messages/in"/>
      <parameter name="in" value="file://C/messages/out"/>
   </templatedRoute>
</templatedRoutes>

I call it with a file that contains: "value" in the body.

Expected output:

valueappendvalue

Actual output:

value{{append}}

Tested this scenario with 3.18.0 and 3.19.0-SNAPSHOT
