Hi,
Thanks for the great addon.
But when I am trying to use HTMLButtonRenderer, I am getting this error:
java.lang.ClassNotFoundException: com.vaadin.shared.ui.grid.renderers.AbstractRendererState
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1891)
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1734)

Do we need to add anything in the wigetset?

Thanks for feedback. Your exception indicates that one of the framework classes is not found, which indicates that something is not quite right in your setup. Can you open ticket in issue tracker with more info.
