[Flex-WCF] Complex type result ArrayCollection contains ArrayCollection

[Michael Baird]

Hi,
I have a Flex 4.6 project communicating with .NET 4.5 through WCF
WebServices. I've been struggling with passing complex types from .NET to
Flex - they were always returning as ObjectProxy until I found this tip[1]
about using the SchemaTypeRegistry to map classes.

Now I have the root types returning correctly, but if the type contains a
List<T>, the first element is another ArrayCollection (or Array if I have *
makeObjectsBindable=false*). So I end up with:

result ->
    MyType
        listOfItems : ArrayCollection (correct)
            [0] ArrayCollection (extra - wrong)
                ItemA
                ItemB
                ...

This is what I am expecting:

result ->
    MyType
        listOfItems : ArrayCollection
            ItemA
            ItemB
            ...

The SOAP response is correct and doesn't contain the nested collection, so
I think it is something in the decoder. Is there a property or
configuration I can try to fix this?
