thanks for your time Tracy, yes absolutely the whole shooting match is sent to
the _one_ call to the function i.e. lstRepRankDrill, which is actually more
than the dataprovider which is {lstRepRankDrill[0].record}. 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. No answers to them :-(
