Use Vaadin Charts in a exisiting Project without widgetset

Hi all,

I try to use Vaadin Charts in a exisiting Project without widgetset. How can I create and add widgetset to the exisiting project?
I use the follows system:

  • eclipse Luna Java IEE SP1 with bugfix E4 RCP Patch (bugzillas 445122) 1.0.0
  • JBoss 7.1
  • jre 1.7

When I try to create a new widgetset with File/New/Witgetset I bacame a java.lang.NullPointerException, this when I doubleclick of Vaadin Witgetset and when I click of next, nothing will happens. What is reason?

I have also create a new project with widgetset how is explained here It works fine.

In the exisiting project I have many settings and also a openshift application and I will not create a new widgetset project and include the source. Better would be to add a new widgetset.

In the attachment is my pom.xml

I try also to copy manually the MyAppWidgetset.gwt.xml from the other demo charts project in the existing project com.waks.main, but when I make vaadin:compile I receive follow error:

No plugin found for prefix ‘vaadin’ in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo]
available from the repositories [local (C:\Users\Antonio.m2\repository), vaadin-addons (, vaadin-snapshots (, Codehaus Snapshots (, central (]
