I don't want to cause too big a stir, but this kind of situation is pretty common when you mix a loosely typed Collection object such as a Map with cross-language serialization and dynamic class loading (the gateway has to use Java reflection to load the object, traverse the object map, etc). Then when you get the Map, how will you type cast the Java object into AS?
I guess what I am getting at here is, I would avoid such loosely typed Collection objects for passing across the wire. Can you create your own Java class to hold the values and return a more traditional Value Object rather then a Map? -- Dave Wolf Cynergy Systems, Inc.
