Oops yeah I misread that conditional + loop code.
But you ARE mangling your xml. The default resultFormat of HTTPService is "object", which causes flex to convert your xml into a nested object structure. Such a structure is hard to debug and is less flexible than xml. I advise using resultFormat="xml". Type projectArray as XMLListCollection. Then in the result handler do: var xmlResult:XML = XML(event.result); trace(xmlResult.toXMLString()); //to verify your structure projectArray = new XMLListCOllection(xmlResult.projects.project); trace(projectArray.length); //to verify your list Now, the dg.selectedItem will hold a <project> node. You could bind directly to the selectedItem, but for easier troubleshooting, I would declare a var(XMLList) to hold the detail dataProvider(s), and assign them in a change handler of the dg: var xmlItem:XML = XML(event.target.selectedItem); trace(xmlItem.toXMLString()); //to verify your item structure _xlResources = xmlItem.resources.item Bind the repeater to _xlResources.
