I have created a custom node type and I need to cast to it during the workflow
execution.
However, when I cast the result of calling token.getNode() to my custom type, I
get a ClassCastException, although the token is at my custom node at the time.
My code is complicated so I created a simple test case, and added it to the
already existing GraphSessionDbTest.java (basically I just added three
assertions to the existing test case).
The test case breaks, in the third assertion. The node has name 's' but it is
not an instance of StartState...
| // added to jbpm-3.1/src/java.jbpm.test/org/jbpm/db/GraphSessionDbTest.java
|
| public void testUpdateProcessInstance2() {
| ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(
| "<process-definition>" +
| " <start-state name='s' />" +
| " <node name='n' />" +
| "</process-definition>");
|
| processDefinition = saveAndReload(processDefinition);
|
| ProcessInstance processInstance = new
ProcessInstance(processDefinition);
|
| processInstance = saveAndReload(processInstance);
| long pid = processInstance.getId();
|
| //this is the actual part added to the already existing
testUpdateProcessInstance() case
| assertNotNull(processInstance.getRootToken().getNode());
| assertTrue(processInstance.getRootToken().getNode() instanceof Node);
| assertTrue(processInstance.getRootToken().getNode() instanceof
StartState);
|
| assertEquals("s", processInstance.getRootToken().getNode().getName());
|
processInstance.getRootToken().setNode(processInstance.getProcessDefinition().getNode("n"));
|
| processInstance = saveAndReload(processInstance);
| assertEquals("n", processInstance.getRootToken().getNode().getName());
| assertEquals(pid, processInstance.getId());
| }
|
|
Is this normal?
I am not a hibernate expert.
In my normal code (not when I am running the simple test case), during the
execution of signal() I get hibernate warnings of the type:
14:01:34,429 [main] WARN StatefulPersistenceContext : Narrowing proxy to class
org.jbpm.graph.node.StartState - this operation breaks ==
|
Are these relevant?
