Is it me or am I missing something... In the example I notice your NOT calling the send() for the HTTP Service And when I get a Object Object back I generally look into the dot(.) notation to make sure I have it set to the right level
Exam: if not category.result try category.result.data etc... Another way to handle it is to drop the results into a model and use the model. Be sure to add the Array utility to the results or you'll be searching forever to find a way to get all the data to present itself JT -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Houser Sent: Sunday, December 18, 2005 4:07 PM To: [email protected] Subject: [flexcoders] HTTPService and XML ( I also posted this on the labs forums at Macromedia.com, so I apologize if this is a cross post for anyone ) I'm using Flex Builder 2 (Alpha, of course) and am having trouble retrieving / accessing XML data. I'm completely new to Flex, but know web programming well. I succesfully implemented the quick start demos without any problem. My long term goal is to populate a combobox from an XML document. I know there is another post on the lab forum on that, but I haven't gotten far enough to be able to apply that post. I set up this quick demo to demonstrate the problem: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml"; xmlns="*"> <mx:HTTPService id="category" url="http://www.jeffryhouser.com/flex/getcategories.cfm"; useProxy="false"/> <mx:Canvas width="100%" height="100%"> <mx:Label x="12" y="24" text="{category.result}" width="253"/> </mx:Canvas> </mx:Application> The label is blank. I would have expected it to return something like "object Object", which makes me think that the problem is in retrieving the data. If I add a similar label to the BlogReader quick start code, "object Object" is returned, like this: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml"; xmlns="*" initialize="feedRequest.send()" > <mx:HTTPService id="feedRequest" url="http://www.jeffryhouser.com/rss.cfm?mode=short"; useProxy="false"/> <mx:Canvas width="100%" height="100%"> <mx:Label x="20" y="10" text="{feedRequest.result.rss.channel.title}" /> <mx:Label x="331" y="9" text="{feedRequest.result}" width="330"/> <mx:DataGrid x="20" y="40" id="dgPosts" width="400" dataProvider="{feedRequest.result.rss.channel.item}"> <mx:columns> <mx:DataGridColumn headerText="Date" columnName="pubDate" width="150" /> <mx:DataGridColumn headerText="Posts" columnName="title"/> </mx:columns> </mx:DataGrid> <mx:TextArea x="20" y="204" width="400" htmlText="{dgPosts.selectedItem.description}" height="200"/> <mx:Link x="24" y="405" label="Read Full Post" height="20" click="getURL(dgPosts.selectedItem.link);" /> </mx:Canvas> </mx:Application> Now, If I take my first example and replace the HTTPService URL to point to an RSS feed; nothing is returned; here is that code: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml"; xmlns="*"> <mx:HTTPService id="category" url="http://www.jeffryhouser.com/rss.cfm?mode=short"; useProxy="false"/> <mx:Canvas width="100%" height="100%"> <mx:Label x="12" y="24" text="{category.result}" width="253"/> </mx:Canvas> </mx:Application> I do not see any differences, in technique, between the BlogReader and the Test code; so I'm not sure why nothing appears to be getting returned. Any thoughts or assistance would be welcome. -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
