Description

The CollectionReader actor reads in an XML representation of the input to a COMAD workflow and translates the Collection, Data, Metadata, Parameter elements etc into tokens that serve as input to the rest of a workflow.

A bug has emerged that prevents these input files from containing Metadata or Parameter elements. The exception thrown for a Parameter element is:

java.lang.NullPointerException
