Peter, You are right, the Map data is actually coming back intact; it is the debug console output that is omitting the data. So there's no problem here except that the trace output is erroneous.
I'm not coercing anything to a String; the output you see is what one normally sees when running the Flash Player in debug mode with AMF logging enabled. I rely on these printouts a lot for debugging. I guess the AMF tracing code built into the player doesn't handle this case properly. Thanks much for your assistance, . . . . ...j Peter Farland wrote: > Are you coercing the Array to a String (say, via simple concatenation) > in a trace()?
