Janarthanan K S [http://community.jboss.org/people/janashanmug] created the discussion "Fork activities with assignment handlers" To view the discussion, visit: http://community.jboss.org/message/547291#547291 -------------------------------------------------------------- Hi The fork activities does not end in join while using assignment-handlers in the tasks. Following is my jpdl. It seems the control does not goes beyond the task "Parallel Queue". Is the way I handle the fork is correct? ------------------------------------------------------------------------------- hello_world.assignee.jpdl.xml ------------------------------------------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <process name="helloWorld" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl"> <start g="27,248,80,40"> <transition to="fork1"/> </start>    <fork g="158,247,91,65" name="fork1">       <on continue="exclusive" event="printHelloEnd"/>       <transition g="182,486:" to="Parallel Queue"/>       <transition g="182,61:121,-15" name="world" to="printHelloWorld"/>    </fork>    <join g="513,267,61,49" name="join1" continue="exclusive">       <transition to="printHelloEnd"/>    </join>    <task g="224,457,211,57" name="Parallel Queue">    <assignment-handler class="cos.workflow.helloworld.HelloWorldAssignmentHandler"/>       <transition g="537,487:" to="join1"/>    </task> <java class="cos.workflow.helloworld.Printer" g="468,42,138,40" method="printHelloWorld" name="printHelloWorld">       <transition g="13,-27" name="join" to="join1"/> </java>    <java class="cos.workflow.helloworld.Printer" g="664,268,116,48" method="printHelloEnd" name="printHelloEnd"> <transition to="theEnd"/>    </java> <end g="893,269,80,40" name="theEnd"/> </process> ------------------------------------------------------------------------------- cos.workflow.helloworld.Main ------------------------------------------------------------------------------- public class Main { public static void main(String[] args) { // Build jBPM services ProcessEngine processEngine = new Configuration().setResource("workflow.jbpm.cfg.xml").buildProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); ExecutionService executionService = processEngine.getExecutionService(); // Deploy helloWorld process definition and start a process instance repositoryService.createDeployment().addResourceFromClasspath("hello_world.assignee.jpdl.xml").deploy(); ProcessInstance processInstance = executionService.startProcessInstanceByKey("helloWorld"); TaskService taskService = processEngine.getTaskService(); String pid = processInstance.getId(); List < Task > taskList = taskService.findPersonalTasks("admin");         Task task = taskList.get(0);         taskService.completeTask(task.getId());         processInstance = executionService.findProcessInstanceById(pid); } } ------------------------------------------------------------------------------- cos.workflow.helloworld.HelloWorldAssignmentHandler ------------------------------------------------------------------------------- public class HelloWorldAssignmentHandler implements COSAssignmentHandler { /** * */ private static final long serialVersionUID = 1L; String userId; /* (non-Javadoc) * @see org.jbpm.api.task.AssignmentHandler#assign(org.jbpm.api.task.Assignable, org.jbpm.api.model.OpenExecution) */ public void assign(Assignable assignable, OpenExecution execution) throws Exception { userId = "admin"; System.out.println("cos.workflow.helloworld.HelloWorldAssignmentHandler"); assignable.setAssignee(userId); } } ------------------------------------------------------------------------------- cos.workflow.helloworld.Printer ------------------------------------------------------------------------------- public class Printer { public void printHelloWorld() { System.out.println("<---------------->"); System.out.println("   HELLO WORLD!"); System.out.println("<---------------->"); } public void printHelloEnd() { System.out.println("<---------------->"); System.out.println("   HELLO END!"); System.out.println("<---------------->"); } } Thanks Jana. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/547291#547291] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
