Vaadin 8 + compatibility = widgetset implementation missing for v7 componen
Hi, good to know that you are enjoying the new version :) Check the following:
- You have to replace the vaadin-server dependency with vaadin-compatibility-server.
- If you are using the default widgetset (you are not compiling it by yourself):
- Replace the vaadin-client-compiled dependency with vaadin-compatibility-client-compiled.
- Add @Widgetset("com.vaadin.v7.Vaadin7WidgetSet") to your UI implementations.
- If you are using a custom widgetset:
- Replace the vaadin-client dependency with vaadin-compatibility-client.
- Recompile it.
If you are using Vaadin Charts, that means you have a custom widgetset, so you cannot use the "default" Vaadin7Widgetset. I assume you have a module descriptor, say com/example/Widgetset.gwt.xml file. there, you should have at least:
<inherits name="com.vaadin.DefaultWidgetSet" />
<inherits name="com.vaadin.v7.Vaadin7WidgetSet" />
<inherits name="com.vaadin.addon.charts.Widgetset" />
When compiling with Maven this should be done automatically. You should also have the following in you UI implementation:
@Widgetset("com.example.Widgetset")
public class YourUI extends UI { ... }
I tested it, and it works :) For completeness, here's the full dependencies section of the pom.xml file I used:
<dependencies>

<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>

I thought the dark days of XYZWidgetset.gwt.xml have ended since vaadin 7.7 - I for sure was glad having the configuration simplified. Too bad I had to reintroduce it again, is this temporary ?
Anyways I managed to have everything up and running according to your instructions.
However... everything is fine when using 8.0.0.beta1, but when I switch to 8.0-SNAPSHOT (which is what I REALLY want), I get an OutOfMemoryError:
