Two things: - Try stuffing the raw XML into a TextArea to see what it looks like. You could bind it directly to the ADG without first converting to array/arraycollection; that's the beauty of the e4x format you're using on the HTTPService call. Not sure why you're doing the conversion to an array and then to an arraycollection. If you need to modify the values when they're displayed, try using the labelFunction on each column. - When I run into issues in code, I try to make it as simple as possible, make sure that works, then add the additional pieces back in one by one until I can see what's causing it to act funny.
I'm thinking something's not quite right with the data after you manipulate it. Look at that piece. -Alex --- In flexcoders@yahoogroups.com, "todd.bruner" <[EMAIL PROTECTED]> wrote: > > Hello and thanks in advance for any help you can provide this flex > newbie. > > I'm trying to create a simple AdvancedDataGrid that displays XML data > from a web service I wrote.
