Problema con Listener

[Stagisti]

Ecco il codice per intero:

function tracciato() {
	//Visualisazione TRACCIATO
	var myListener4:Object = new Object();
	myListener4.getRows = function(evtObj) {
		//fscommand("Debug", evtObj.data.message);
		file_xml = _level100.filexml;
		var record_xml = new XML(evtObj.data.message);
		var column;
		for (var k = 0; k<record_xml.childNodes[0].childNodes.length; k++){
			column = record_xml.childNodes[0].childNodes[k].childNodes[0];
			IdLez = column.attributes['value'];
			column = record_xml.childNodes[0].childNodes[k].childNodes[1];
			TitLez = column.attributes['value'];
			var query:Object = new Object();
			query.getRows = function(evtObj) {
				fscommand("Debug", evtObj.data.message);
			}
			_level100.myF_ADO2.addEventListener("getRows", query);
			_level100.myF_ADO2.setSQL("SELECT DataInizio, ...Session2");
			_level100.myF_ADO2.open("Session2");
			_level100.myF_ADO2.getRows("-1");
		}
	};
	_level100.myF_ADO.addEventListener("getRows", myListener4);
	_level100.myF_ADO.setSQL("SELECT * FROM TBL_Lezioni", "Session1")
	//_level100.myF_ADO.setSQL("SELECT TBL_Lezioni.Titolo...ull))", "Session1");
	_level100.myF_ADO.open("Session1");
	_level100.myF_ADO.getRows("-1");
	}

Grazie
