Nice suggestion Alex, the compiler was ok, but the runtime chocked: TypeError: Error #1034: Type Coercion failed: cannot convert Object@183e1f101 to model.common.Person.
Then I realized that the object I'm putting in the array is *not actually typed* !! It's coming in from Firebase in JSON format, via ExternalInterface, and added to an array collection without casting. I'm actually surprised that it worked before (i.e: in labels, regular DG fields, etc, etc) !! So, if I actually cast the object to the correct class first (by having a field in the JSON message with the class name, and using that to cast to the correct Object type), then this problem goes away entirely, even this will work: So, the issue is fixed by explicit casting on insertion into the ArrayCollection, but the lessons re "set data()" are valuable. Separately: I'm getting this warning every single time that ExternalInterface receives an object: WARNING: For content targeting Flash Player version 14 or higher, ExternalInterface escapes strings using JSON conventions. To maintain compatibility, content published to earlier Flash Player versions continues to use the legacy escaping behavior. I'm worried about this because some users will be using Flash 11.1 and some will be using more recent versions. What's the best way to ensure that the data I send complies 100% with both string escape algorithms??
