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?

* Action: 'org.jboss.bpm.console.client.process.UpdateInstanceDataAction'
