/**
 * A BeanShell script to execute on a particular event.
 * <p> The script is interpreted on it's event fired<br />
 * in the environment there is available:</p>
 * <ul> <li>event (event type-id)
 * </li><li>fieldId (is a field id associated with event)
 * </li><li>currentValue (is a set of current values)
 * </li><li>currentErrors (is a container for occurred errors)
 * </li><li>currentForm (is a form instance, holding values)
 * </li> </ul>
 * <p>
 * currentValue will be applied to the currentForm, property field</p>
 * </p>
 * <p>
 * This allows to dynamically customize the system by executing custom actions
 * at given extension points where an event is generated.
 * </p>
 * <p>
 * A WorkflowScript needs to be configured to be executed for a particular field
 * of a Project. This configuration is represented as a ProjectScript. <br>
 * WorkflowScript - ProjectScript is a 1-N relationship.
