You'll have to determine why an ObjectProxy is being created... typically it's because an anonymous Object was returned and RemoteObject had makeObjectsBindable="true" (which it is by default). As for why an anonymous Object was returned - either something like a java.util.Map was returned instead of the type you expected, or the com.foo.Expr class was not available to the native deserializer in the Flash Player at the time the response was received. Your AS3 (and Java, for the reverse situation) Expr class must also possess a constructor that allows for no-arguments instantiation. Depending on how classes are being loaded by your SWF (they can be lazily loaded in Flex applications) the underlying call to flash.net.registerClassAlias() (that is generated for you by the mxmlc compiler because you added [RemoteClass(alias="com.foo.Expr")] metadata) may not have executed before the response was received. Another reason is that no reference was made to the ActionScript com.foo.Expr class in your Flex application and hence the mxmlc compiler never linked the class definition into the SWF. I don't think this is the cause as you appear to make a reference to the class in the result handler (and I imagine you also imported this class in order for it to compile). As a last ditch effort you could try making a static reference to your class somewhere in your application, like: private static var dep:Class = Expr; or I guess you could even call flash.net.registerClassAlias on your own and not rely on the generated code. Actually, that begs the question, are you using MXML? Or are you working with a pure ActionScript application? Pete
