Dmenu NoClassDefFoundError
Hi,
I tried to use the Dmenu addon with Vaadin 7.7 and I got this error on runtime.
java.lang.NoClassDefFoundError: com/google/gwt/event/shared/EventHandler
Here are my dependencies in my pom.xml (the vaadin version is managed in the parent pom)
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-server</artifactId>
</dependency>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-push</artifactId>
</dependency>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-themes</artifactId>
</dependency>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-client</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.vaadin.addons</groupId>
<artifactId>dtabs-add-on</artifactId>
<version>0.6.0</version>
</dependency>
<dependency>
<groupId>org.vaadin.addons</groupId>
<artifactId>dmenu-widget</artifactId>
<version>1.12.0</version>
</dependency>
Is there something missing?

Hi Jean-Christophe,
the source code is here: http://source.dussan.org/summary/?r=vaadin/dmenu.git
While you write here https://vaadin.com/directory#!addon/dmenu-widget that it should be recompiled for 7.7 - did you try this yourself, does it fix the problem?
Best Regards,
Enver
