I tried this out by converting a small project that was using elemental 1
to elemental 2. I was able to get it to compile both in dev mode and in a
production compile. But my event listeners weren't firing at all when I
ran it.
Some feedback:
1) Lambda event listeners have to be cast into order to avoid an error from
"javac":
[javac] /Users/john/.../src/com/App.java:208: error: reference to
addEventListener is ambiguous
[javac] doc.getElementById("list").addEventListener("click", event ->
listPressed(event));
[javac] ^
[javac] both method
addEventListener(String,AddEventListenerListenerCallback) in Node and
method addEventListener(String,EventListener) in Node match
You can avoid this error with an explicit cast to EventListener (or
AddEventListenerListenerCallback), but that isn't ideal:
.addEventListener("click", (EventListener)event -> listPressed(event));
2) Some things weren't defined on HTMLElement that I needed, namely:
"outerHTML" and "children". These were available in elemental 1. They can
be added by extending the class like so and casting to it:
@JsType(isNative = true, namespace = JsPackage.GLOBAL)
public class HTMLElementEx extends HTMLElement {
public String outerHTML;
public HTMLCollection<HTMLElement> children;
}
