You can create a predicate that checks the size of the body, and matches if its 1. Camel offers a number of languages that can do this, such as simple http://camel.apache.org/simple .choice() .when(simple("${body.size} == 1")) Alternative languages could be ognl, mvel, groovy etc http://camel.apache.org/languages.html Or write your own java method that checks this and use a method call expression public boolean oneLine(List body) { return body.size() == 1; } > Thanks > > -- > View this message in context: > http://camel.465427.n5.nabble.com/Bug-in-Splitter-Implementation-Camel-2-8-3-tp5713873p5713874.html > Sent from the Camel - Users mailing list archive at Nabble.com. -- Claus Ibsen ----------------- FuseSource Email: cib...@fusesource.com Web: http://fusesource.com Twitter: davsclaus, fusenews Blog: http://davsclaus.com Author of Camel in Action: http://www.manning.com/ibsen
