Error when trying out GWT&Polymer example

[chcklngm]

When going through the example in the GWTProject page, I get the following error in the step where the ripple effect is added. The UI works as expected up until that point.

Error message in Chrome DevTools (screenshot attached) this.get_clientBundleFieldNameUnlikelyToCollideWithUserSpecifiedFieldOkay_0_g$(...).style_3_g$ is not a function

Also in the screenshot is the Refused to get unsafe header "Location" error.

I am using GWT-2.8.1 with vaadin-gwt-polymer-elements-1.9.3.1.

In my app html file I have this in the head tags `

`

I am importing the webcomponents as follows ` List<String> alCollections = new ArrayList<String>(); alCollections.add("iron-icons/iron-icons.html"); alCollections.add("paper-ripple/paper-ripple.html"); Polymer.importHref(alCollections, new Function<Object, Object>() {

	@Override
	public Object call(Object arg) {
		GWT.log("import succeeded");
		startApplication();
		return null;
	}
}, 
new Function<Void, Void>() {
	@Override
	public Void call(Void arg) {
		GWT.log("import failed");
		return null;
	}
});
}

`

Main.java ` public class Main extends Composite {

interface MainUiBinder extends UiBinder<HTMLPanel, Main> {}

private static MainUiBinder ourUiBinder = GWT.create(MainUiBinder.class);

public Main() {
	initWidget(ourUiBinder.createAndBindUi(this));
}

}`

Main.ui.xml ` <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui' xmlns:p='urn:import:com.vaadin.polymer.paper.widget' xmlns:i='urn:import:com.vaadin.polymer.iron.widget'>

Removing the <ui:style> section in the Main.ui.xml file fixed the problem of the page not rendering.

The 'Refused to get unsafe header "Location"' error is still there.
