public class FlowUtils
extends Object

This is a utility class to aid in the submission flow scripts. Since data validation is cumbersome inside a flow script this is a collection of methods to preform processing at each step of the flow, the flow script will ties these operations together in a meaningful order but all actually processing is done through these various processes.
