Can I delete demo data? I tried to delete demo data, but when I startup and shutdown tomcat server their are created again by activiti-explorer web module.
Are your using the trunk source code or a downloaded Activiti version? Because when you delete the demo data it should not appear again the Explorer. It's not created there.
Mainly I downloaded activiti version 5.10 and I ran "ant internal.build.webapps" and "ant internal.db.create". So I moved WAR modules to webapps folder in Tomcat and then I delete demo data. When I startup/shutdown Tomcat server they are inserted again.
