I am concerned about this expression:
ordMedXMLList = resultXML.child("OrdMedList");
Why not:
ordMedXMLList = resultXML.OrdMed; //You'll need the namespace
identifier in there or have a default.
trace(ordMedXMLList.length());

Subject: [flexcoders] Re: DataGrid not populating from XMLListCollection
- namespace issue?
Hi Brian,
These days I usually want to end up with strongly typed objects, so I
generally implement my VO classes so that they accept XML in their
constructor. I pass the XML node to the constructor, throw a "use
namespace" in there and then grab the properties I need from the XML.
HTH,
Ben
