Have you tried to run your code in superdev-mode or compiled ?

It seems i can no longer instantiate objects as i was doing before since using Elemental.

I'm getting errors on this line for some reason:

Image imgPlay = new Image("img/Blue_Play_Button_Pressed_Down.svg");

I tried changing it to Image imgPlay = new Image(); but got the same error. This works fine when i'm not referencing Elemental.

The DevMode console displayed the following:

Please could someone share any thoughts?

Putting gwt-elemental.jar on class path and inheriting elemental.Elemental is fine and it should work.

When you see "failed to load the module" you usually see the reason in the DevMode console. We can't guess reasons.
