This should work as you are expecting.

Are you using "compile_opt hidden" in the methods? Otherwise, I'm not
sure why this would be from what you are describing. Are you sure you
are getting the correct source code file, not an old one? Use "help,
/source" to see what has been compiled in your current IDL session.

You shouldn't ever have to manually compile things if you have named
them correctly. You also shouldn't have to use obj->classname::method
unless you are trying to get the superclasses' method.
