Re: Java DSL / GroovyExpression / Binding
You are welcome to provide patches and improve the groovy dsl.

Is there any chance to extend the binding of a GroovyExpression? Currently (in camel 2.11.1) the Groovy binding is defined on runtime based on the exchange only and I did not find an extension point. My current solutions is to use a GroovyExpression2 class which is a copy of the original class and provided a new constructor method accepting a MapString,Object parameter which is added to Binding. This allows me to add additional parameters at time of route creation but I doubt this is the right way. Due to the fact createBinding method is private and not protected I can not derive from GroovyExpression and need to copy the class.
