This is my first comment at the community, I just hope I've writted in the correct place

I've installed jbpm using ant demo.setup.tomcat, after the installation all seems to work correctly, but when I try to process instance data i receive this error

Any suggestion?

    * URL: ' http://localhost:8080/gwt-console-server/rs/process/instance/AsyncActivity.10001/dataset http://localhost:8080/gwt-console-server/rs/process/instance/AsyncActivity.10001/dataset'
    * Action: 'org.jboss.bpm.console.client.process.UpdateInstanceDataAction'
    * Exception: 'class com.google.gwt.http.client.RequestException'
