Speaking of multinames, what is the ABC code generated by the Flex compiler for the two cases? It might contain some clues. I would have expected both to return "1" and the node. But I did see in the spec the notion of "InScopeNamespaces". I generally hate reading specs like these so I am not very knowledgeable about what the spec says.

I have been focused on each portion of the spec as I create unit tests and verify things between the player and the Royale implementation. I've also glanced a few times in the avmplus code, and that has provided some clues where things were intentionally implemented slightly off spec, but still a few things to figure out. However I am making progress - I think I have everything covered for the codebase I am working on.... but I will keep going beyond that. For that example above, I might be wrong, but I suspect it is using a multiname with default namespace included for the explicit call case in the player, but not for the implicit one, but I am not yet sure why. I will double-check the spec though... On Thu, Sep 5, 2019 at 4:02 AM Alex Harui <[email protected]> wrote: > Don't know.
