I have jbpm set up using the in memory HSQL DB. I have written a simple unit test creating process variables on the context instance loke so : ProcessDefinition definition = jbpmContext.getGraphSession().getProcessDefinition(Long.parseLong(instanceTO.getTemplateId())); ProcessInstance instance = new ProcessInstance(definition); ContextInstance contextInstance = (ContextInstance) instance.getInstance(ContextInstance.class); contextInstance.setVariable(name,"name"); contextInstance.setVariable(test,"test"); jbpmContext.save(instance); However when I load the instance again, those variables do not exist. Debugging into my code I find that when the variables are created they exist in a transientInstances list while the instances list remains null. I dont know why these variables are not being persisted. any ideas ? Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135347#...
