JADE Environment Development Ideas

Nice idea. I've encountered this situation a few times myself, and used a script similar to the following to find the schemas which have subschema copies of the class of interest:

findSubSchemaCopyClass() protected;

constants
    TheClassName : String = "YourClassNameHere";

vars
    cls : Class;

begin
    foreach cls in Class.instances where cls.name = TheClassName do
        if cls.superschemaType = null then
            // This is the actual class definition in some super schema, so ignore this one
            continue;
        endif;

        write "Found subschema copy of '" & TheClassName & "' in schema: " & cls.schema.name;
    endforeach;
end;
