 * @deprecated use ProcessElement because it has many impact to use the FlexoProcessNode instead (one of the main reason is that getObject
 *             returns a FlexoProcessNode instead of a FlexoProcess and many actions are registered on the FlexoProcess and not on
 *             FlexoProcessNode)
