[jboss-dev-forums] [Design of JBoss jBPM] - custom node-type derived from superstate produces hibernate

Hello, I'm trying to create a custom node type called my-step which should be a container like super-state. I'm using jbpm-3.1.4 and set up the junit test case scenario from the documentation, chapter "3.2. Database example". I changed the method "deployProcessDefinition": i switched "JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();" to be the first statement in this method, so that "...ProcessDefinition.parseXmlString..." uses the config defined in the unit test and not some default settings. Then I changed the config to point to my node-types.xml where I added this line: <node-type element="my-step" class="test.Step" /> The class looks like this: | package test; | | import org.jbpm.graph.def.SuperState; | | public class Step extends SuperState { | | private static final long serialVersionUID = 1L; | | public Step() { | System.err.println("Hello there."); | } | | public Step(String name) { | super(name); | System.err.println("Hello: " + name); | } | } | I changed the process definition and wrapped the state into super-state. When I run it, everything works as expected. When I change super-state into my-state, I get the following hibernate exception (shortened) after my output "Hello there.": | org.jbpm.persistence.JbpmPersistenceException: couldn't commit hibernate session | ... | Caused by: org.hibernate.HibernateException: instance not of expected entity type: test.Step is not a: org.jbpm.graph.def.Node | ... | I don't understand this. Step extends SuperState and SuperState extends Node, so Step is a Node - isn't it? Do I need a hibernate mapping for my class? What should it look like? Maybe it is not supported to extend SuperState? I don't like to copy the SuperState class. In fact it is not possible because the class uses the superstate field from Node which is not accessible from a copy... What can I do? Is it a bug? -- Regards, Daniel View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4012428#...
