I received this error in the drools workbench when creating a new project:

Unable to complete your request. The following exception occurred: java.lang.NoSuchMethodError:org.guvnor.common.services.project.events.NewProjectEvent.(Lorg/guvnor/common/services/project/model/Project;Lorg/uberfire/rpc/SessionInfo;)V.

The project was not created but once I refreshed the browser it showed up. Should I assume my project is corrupt or is it valid?

This is on 6.0.1 final (with the merged deployment changes).

Thanks

Joe
