Vaadin 8 compatibility

[clavaud]

Dear,

We're currently trying to integrate Microservice with their own GUI, but facing some difficulties with Vaadin.

I'm trying to use you component, but getting errors and I don't know if they are related to my usage or the incompatibility with Vaadin 8.

Could you help ?

Best regards

Alexandre

Some code
@Springview(name = AdUserView.VIEW_NAME)
@uiscope
public class AdUserView extends VerticalLayout implements View {
public static final String VIEW_NAME = "AdUserView";
private static final long serialVersionUID = 1L;

public AdUserView() {
	final VaadinUIComponent browser = new VaadinUIComponent( "http://localhost:8081/users/" );
	browser.setSizeFull();
	setSizeFull();
	addComponent( browser );

}

@Override
public void enter(final ViewChangeListener.ViewChangeEvent event) {
	Notification.show( "AdUserView::Enter" );
}

}

Thanks for reporting. Please let me know if 2.1 fixes this.

Dear,

Works great for Vaadin 8, very good job.

As I would like to migration my application to Vaadin 10, how to do the same thing with Vaadin 10 ... ?

Best regards

Alexandre

There are no current plans to migrate this to Vaadin 10. Please "thumbs up" this issue if you are interested in having support for it in Vaadin Flow: vaadin/flow#4316

[clavaud]

OK, then do you have any idea or tips on how to get the same behavior with Vaadin 10? I have a microservice application with an ui for each service. I was using your component to federate all ui in one application using a left menu go access microservice and the center page to display the remote ui... Using Vaadin 8, everything is working as expected, even using oauth2 (I did a change on your lib to handle it).
