Description

See nabble
http://camel.465427.n5.nabble.com/Invoking-a-bean-returned-by-a-previous-bean-invocation-tp5676696.html

The example with the nested animal parameter.
We should see if we can better detect this use-case, and avoid the intermediate String conversion, when its a parameter type.

       public void testBodyOgnlOnAnimalWithOgnlParams() throws Exception {
               exchange.getIn().setBody(new Animal("tiger", 13));
               exchange.getIn().setHeader("friend", new Animal("donkey", 4));
               assertExpression("${body.setFriend(${header.friend})}", null);
       }

Fails with org.apache.camel.NoTypeConversionAvailableException: No type
converter available to convert from type: java.lang.String to the required
type: org.apache.camel.language.simple.SimpleTest.Animal with value donkey
