I didn't found any camel convertor from org.apache.camel.component.flatpack.DataSetList to anything so I created one to convert to an ArrayList. A standard camel converter for this would be handy.

These "special records" are supported in de DataSetList BUT only if header/trailing id's "header" and "trailer" are used. Any other id's will fail and that is a petty since it is possible to have it more flexible.
