Adobe Flex: Cannot Convert XMLList to mx.collections.IList

Question

My Flex app runs a service to a php page that pulls data from my database, then structures the result in an XML format. I created a new XMLList called testList outs

Answer 1

You probably are using this inside a module or a swf that you've loaded, and the loader has a different applicationDomain than the parent, and some other loaded module or swf is also using XMLList or XMLListCollection. Without more details on your architecture, I can only tell you to make sure the parent applicationDomain loads in XMLList and/or XMLListCollection before either child, or make sure they both share the parent's applicationDomain.
