Why are Java value objects coming back as Generic Flex objects?
Question
I will try to give as much detail as I can.
I am creating an CRM application using Flex(Cairngorm 2)/Java/Hibernate. The basic problem I am having is this:
I have a Customer class in Java that has an ArrayList of Address classes. I have a Customer class in Flex that has an ArrayCollection of Address classes.
When I make the remote object call for a Customer I get back a Customer object in Flex, but the ArrayCollecion objects have a data type of Object instead of Address.
If I try to call for a List of Address classes I get the same result. If I try to call for a List of Customer classes I get a list of Customer classes in Flex.

You should refer your Address class somewhere in SWF. The best way to do it is to declare a field in main application:
private var references:Object = {addressClass:Address, someOtheClass:SomeOtherClass};
The problem is that ArrayCollection in ActionScript hasn't type reference (generics in Java). So class' bytecode isn't included in SWF.
