that same can be done in jbpm4 with changing the file (jbpm.jpdl.activities.xml) that references the task activity (no factory needed). That is what rams.rapo meant. You might need to change ./pvm/src/main/resources/jbpm.task.hbm.xml as well but that might depend on what you want. What is even greater, you can change more of the behaviour of the task in jbpm.jpdl.activities.xml But keep in mind that this part is not fully stabilized yet View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4251085#...
