The problem I think is you're using the wrong data structures.
If your Java map looks like this:
HashMap<int, String> myMap;
What you'll get in Flex isn't what you've got below, it's an object like
this:
var mymap : Object =
{
1: "String 1",
2: "String 2",
79: "Blue"
}
Not the structure that you're trying to coerce it to based on the code you
posted. But since this is clearly just "example" Flex code and I have no
idea about what your Java looks like, I'm just guessing.
