All Implemented Interfaces:

Serializable

public class DynamicItemDynamicTask
extends DynamicItem

Dynamic Item for dynamic dynamicTask. This Class do sth different than other Dynamic Item Class. Here we call the method executeDynamicItem(), which substitute the old OJElement OJDynamicItem object with a list of mbase References. Details are descripted by Javadoc of method. In this Class we don't overwrite any method of it's super-super class Item, because after instanciating(performed executeDynamicItem()) there's no more nessesary to store this Object in ContentManager and this Object exists no more. Note: It's dangerous to try to call any herited method like getTextualDOM() to this Object.
