I started a new thread to continue this issue because I had gotten past the 'Unknown Property' error with the handlers. I wanted the new thread to be more specific to the problem, which has evolved into DataGrid not populating from XMLListCollection and namespace issues.
Here's the new thread: http://tech.groups.yahoo.com/group/flexcoders/message/93492 The 'OrdMedList' node is there in the original post. But a quick answer to your question, here's what the structure looks like, w/out the namespaces: <OrdMedList> <OrdMed> <id>5</id> <desc>tylenol</desc> </OrdMed> <OrdMed> <id>97</id> <desc>advil</desc> </OrdMed> ... </OrdMedList> This is the output of the trace() on my XMLListCollection. I also implemented a labelFunction to try to deal with the namespace issue, and found a weird result: there are 10 OrdMed nodes in my list, but the length of OrdMedList is 1 and the labelFunction is invoked 4 times, 2 each for id and desc. --- In [email protected], "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > What does an "OrdMedList" node look like?
