Users would expect to have events with source from where event was fired. That was source field in GWT events. In your implementation we will need to intercept DOM event and fire new event with source field of custom element. (e.g re-fire through EventHandler). This is kind of double work.
Another thing that we need to care about is if add and then remove some custom element from DOM like *element.removeChild(customElement.asElement()) *we also need to remove reference to custom element to be garbage collected? Since only *asElement() *is removed from DOM not custom element object itself. If I'm right... This is why it would be good if custom element can extends Element and wrap inner element like Widget Composite. Btw: Great work there with Elemento especially HTML Templates On Wednesday, October 11, 2017 at 1:54:57 PM UTC+2, Harald Pehl wrote: > > We still use the GWT event bus for custom / application scoped events.
