RE: [flexcoders] XML charting troubles

[Tracy Spratt]

I advise setting resultFormat=”e4x”, doing away with binding into the mx:Model, and instead using a result handler handler to assign the result directly to an instance/global XML variable.   This way, you can trace the contents of event.result.toXMLString(), and see exactly what you have in Flex.   Mx:Model converts the xml into a nested mx:Object structure.  Dumping its content is harder than toXMLString().   If you need a collection for a list-based control dataProvider, use an e4x selection _expression_ to return an XMLList, and wrap that in an XMLListCollection.   Tracy   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of dataknife Sent: Wednesday, November 01, 2006 3:39 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] XML charting troubles   All, I'm a Flex Newbie - coming from the Java world (nice to not have to use JSP's any more!)..
