"blocking task in start-state does not block" To view the discussion, visit: http://community.jboss.org/message/600661#600661 -------------------------------------------------------------- Hi, I'm running into the problem that a blocking task in a start-state node does not prevent a token to proceed to the next node, but a "regular" blocking task in a task-node does. I'm using the jBPM 3.2 runtime included with the latest JBoss SOA-P 5.1. The below JUnit test code illustrates the problem. There are two test cases; the only real difference is that the one tests a blocking start task and the other tests a blocking "regular" task. For me, the first test case fails but the second one succeeds. The way they are written, I would expect this to be the other way around. I understand from {thread:id=390489} that creating a new ProcessInstance will not automatically create a TaskInstance for the task defined in the start-state, if any. While this strikes me as odd, I can accept that is the way things work. However, once I manually create the StartTaskInstance, I do expect it to block progress to the next node. {code} package nl.travelcard.das.workflow; import java.util.HashMap; import java.util.Map; import junit.framework.TestCase; import org.jbpm.graph.def.ProcessDefinition; import org.jbpm.graph.exe.ProcessInstance; import org.jbpm.taskmgmt.exe.TaskInstance; import org.junit.Before; import org.junit.Test; public class JbpmTest extends TestCase { private ProcessDefinition pd; @Before public void setUp() { this.pd = ProcessDefinition.parseXmlString( "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" + "<process-definition xmlns=\"\" name=\"blockingStartTask\">" + " <start-state name=\"start\">" + " <task blocking=\"true\" name=\"blocking task in start node\"></task>" + " <transition to=\"task\"></transition>" + " </start-state>" + " <task-node name=\"task\">" + " <task blocking=\"true\" name=\"blocking task in task node\" ></task>" + " <transition to=\"end\"></transition>" + " </task-node>" + " <end-state name=\"end\"></end-state>" + "</process-definition>" ); } @Test public void testBlockingStartTask() { ProcessInstance pi = pd.createProcessInstance(); //I would have expected a task instance to have been created by now; I guess that's not how it works. //assertEquals("expected task was not created", 1, pi.getTaskMgmtInstance().getTaskInstances().size()); TaskInstance ti = pi.getTaskMgmtInstance().createStartTaskInstance(); assertEquals("expected task was not created", 1, pi.getTaskMgmtInstance().getTaskInstances().size()); assertEquals("task has wrong name", "blocking task in start node", ti.getName()); assertTrue(ti.isBlocking()); assertTrue(ti.isStartTaskInstance()); assertTrue(pi.getTaskMgmtInstance().hasBlockingTaskInstances(pi.getRootToken())); try { pi.getRootToken().signal(); fail("task that should be blocking nevertheless did not block"); } catch (IllegalStateException e) { assertEquals("state changed despite blocking task", "start", pi.getRootToken().getNode().getName()); } assertEquals("start", pi.getRootToken().getNode().getName()); } @Test public void testBlockingRegularTask() { ProcessInstance pi = pd.createProcessInstance(); assertEquals("start", pi.getRootToken().getNode().getName()); pi.signal(); //this ought to go wrong, but it doesn't (see previous test case) assertEquals("task", pi.getRootToken().getNode().getName()); assertEquals("expected task was not created", 1, pi.getTaskMgmtInstance().getTaskInstances().size()); TaskInstance ti = pi.getTaskMgmtInstance().getTaskInstances().iterator().next(); assertEquals("task has wrong name", "blocking task in task node", ti.getName()); assertTrue(ti.isBlocking()); assertFalse(ti.isStartTaskInstance()); assertTrue(pi.getTaskMgmtInstance().hasBlockingTaskInstances(pi.getRootToken())); try { pi.getRootToken().signal(); fail("task that should be blocking nevertheless did not block"); } catch (IllegalStateException e) { assertEquals("state changed despite blocking task", "task", pi.getRootToken().getNode().getName()); } assertEquals("task", pi.getRootToken().getNode().getName()); ti.end(); assertEquals("end", pi.getRootToken().getNode().getName()); } } {code} Any thoughts?
