I tried accessing that object, Fields is null.. here is the logic (I confirmed the selectedCenterlineUrl is corrrect):
var selectedCenterlineUrl = this.HierarchyTableCenterlineSelect[this.HierarchyTableCenterlineSelect.selectedIndex].value;
var centerlineFeatureLayer = new FeatureLayer(selectedCenterlineUrl);
centerlineFeatureLayer gets created but fields is null..Why?
