I've taken the working sample that I've shown in #383 and tried to run it in engine-seed (off of commit d317ce45cb). The only change I've made to the source is change the famous.*.* dependencies to require('famous/*/*') format. Now instead of the code running like you'll see if you paste the example from #383 into a famous.org editor, you'll see this error:
Uncaught Error: This node does not have access to a transform component
Here's a link to the branch of my engine-seed fork where this error happens: https://github.com/trusktr/engine-seed/tree/position-bug
If you change line 116 from
let cardNode = scene.addChild(new BetterNode)
to
let cardNode = scene.addChild(new Node)
You'll notice that not using the extended Node class results in the error going away! (I was lacking a name for the extended Node so, BetterNode. 😆)
