I'm not having success with your suggestions.
The configuration below allows creation of tasks upon entering the
NotifyApprovers
node but the node does not block and the Assignment handler is never called.
I can view the tasks by accessing the (terminated) process instance by calling
| ProcessInstance pi
| pi.getTaskMgmtInstance().getTaskInstances()
|
| <task-node name="NotifyApprovers" create-tasks="false" signal="true">
| <task name="ApproveDocument" blocking="true">
| <assignment
class="workflow.assignment.ApproveDocumentAssignmentHandler"
config-type="bean"></assignment>
| </task>
| <event type="node-enter">
| <action name="CreateTasks"
class="workflow.action.CreateApproverTasksAction" config-type="bean"></action>
| </event>
| <transition name="Process" to="ExecuteDocument"></transition>
| </task-node>
|
Is there something specific I need to do when creating my tasks that would
enable blocking at the task-node?
The configuration below blocks upon entering the NotifyApprovers node and
calls the Assignment handler. An ApproveDocument task is created but not
filled with any data (everything except the name is null or empty) and I
cannot access the task through the process instance. Calling
| ProcessInstance pi
| pi.getTaskMgmtInstance().getTaskInstances()
|
generates an exception.
org.hibernate.HibernateException: null index column for collection:
org.jbpm.graph.exe.ProcessInstance.instances
| <task-node name="NotifyApprovers">
| <task name="ApproveDocument">
| <assignment
class="workflow.assignment.ApproveDocumentAssignmentHandler"
config-type="bean"></assignment>
| </task>
| <transition name="Process" to="ExecuteDocument"></transition>
| </task-node>
