I have A POJO with various Integers, Floats and .. as well List<String>. If I return such an object what I finally get in AS3 is incomplete.
The AS3 object's properties for the List<String> are NULL. The AS3 class has an Array variable. If I use Vector.<String> in AS3 nothing works at all. It says that some properties on the JAVA object would be marked protected and cannot be accessed. But in fact there is nothing protected.

I don't use "ArrayCollection" or something, because I have to access my persistence object within a loaded SWF (created with CS4 Flash).
But I guess GraniteDS should work with the basic data structures like plain "Array".
