Polymer PaperToast show() method not found?

Hi all,

I’ve hooked up the vaadin polymer widgets with my gwt project. I am using gwt “2.8.0-beta1”. My vaadin gradle import is:


I can use some widgets just fine, such as PaperButton, PaperCard. I’m having trouble showing a PaperDialog or a PaperToast. For example:

PaperToast toast = new PaperToast(); toast.setText("hi"); toast.show(); It seems that the “show()” method cannot be found:

Lcom_vaadin_polymer_paper_PaperToastElement_2(…).show is not a function

Same thing happens with PaperDialog and trying to call its “open()” method.

Does anyone have an idea what I’m doing wrong?
