Make sure your classes adhere to AMF serialization rules. You need public get/set accessors for each property.
You can also use either of the following config settings for your <channel-definition> on the server to further debug any problems with de/serializing your custom types. <channel-definition ...> ... <properties> <serialization> <ignore-property-errors>false</ignore-property-errors> <log-property-errors>true</log-property-errors> </serialization> You could use either (or both); when ignore-property-errors is false, an exception is thrown when a property can't be handled rather than just being ignored (the historic default to match player behavior). When log-property-errors is true, you'll get a warning logged on the server when a property is ignored. If you enable this, add Endpoint.* to your log category filters to see these.

I am now able to send an ArrayCollection of my custom class Chart: [Bindable] [RemoteClass(alias="factory.data.Chart")] public class ChartObject { private var name:String; private var axisList:ArrayCollection; public function getAxisList():ArrayCollection { return axisList; } } And I can read the array in the java message handler, and it even detects the objects in the array as Charts but when I try to get the axisList array from within Chart, it comes up as null. The axisList is an array of objects from another custom class I have called Axis. Here is a sample of the java Chart class for reference: public class Chart { //import mx.collections.ArrayCollection; //import mx.controls.Image; public String name; public ArrayList axisList; public ArrayList getAxisList() { return axisList; } --- In flexcoders@yahoogroups.com, "Seth Hodgson" <[EMAIL PROTECTED]> wrote: > > You can send any type of data as the body of a message.
