problemas con SmartXMLParsing

Cuando habilito SmartXMLParsing en mi treegrid, no funciona correctamente el foreachRow solo puedo accesar a los nodos del nivel 0

forEachRow operator process all row accessible by API
In SmartXMLParsing mode only opened branches parsed from XML and accessible by API, content of closed branches not exists ( and not accessible ) until opening for any grid’s API, including forEachRow method.
