Lets clarify terminology. "dataProvider" must always be a list of some kind, like an array, and XMLList an ArrayCollection or an XMLListCollection. It can not be a single XML node.
This expression should return an XMLList: lstRepRankDrill[0].record If you trace(lstRepRankDrill[0].record.toXMLString()); //what do you see? Does your DG display correctly without the filter?

I know that the fact there is only one call to the filter is significant, but do not know why, unless it is because I have to put the filter on lstRepRankDrill.filterFunction = filterRepRankDtlChnl; and it is hierarchical. Obviously I cannot put the filter on lstRepRankDrill[0].record as it is XML and not an XMLListCollection. Am using DG not ADG if that makes any difference. Eventually found 2 other Google questions out there with the same scenario - one call to the filter with the whole XMLListCollection being passed.
