Key: CAMEL-18070
URL: https://issues.apache.org/jira/browse/CAMEL-18070
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Claus Ibsen
Fix For: 3.x
To make it easy to check that keyName exists or not.
Well its easy to check if it exists but not the opposite
<simple>{{?keyName}}</simple>
We need a not argument for this
<simple>{{?keyName}} == null</simple>
Or something ala
<simple>{{!keyName}}</simple>
<simple>${properties:!keyName}</simple>
