Type analysis for a fully-dynamic language like JavaScript is tricky and there's no guarantee an IDE will be able to resolve it. Autocompletion is very much a best-guess feature. I wouldn't expect tracking properties like this.layer to work as, unless it enforces one particular style of object creation there is no way for an IDE to know what this is.

I would suggest in general using the array literal syntax [] in preference to new Array in almost every case. Don't know if that'll help Netbeans though.

[] instead of new Array is highly recommended for JavaScript.
