This was my mistake I used this attributes in not in <task-node>.
At the end I found solution for my problem:
mapping fragment:
| <task-node name="proposed" end-tasks="true" signal="never">
| <task name="accept">
| <assignment class="orders.workflow.OrdersAssignmentHandler"/>
| </task>
| <task name="cancel">
| <assignment class="orders.workflow.OrdersAssignmentHandler"/>
| </task>
| <transition name="accept" to="accepted"></transition>
| <transition name="cancel" to="canceled"></transition>
| </task-node>
|
Listing avaliable actions for user:
Map<ProcessInstance, List<TaskInstance>> instancesGrouped = new
HashMap<ProcessInstance, List<TaskInstance>>();
| for(TaskInstance task : tasks)
| {
| ProcessInstance process = task.getToken().getProcessInstance();
| List<TaskInstance> instances = instancesGrouped.get(process);
| if(instances == null)
| {
| instances = new ArrayList<TaskInstance>();
| instancesGrouped.put(process,instances);
| }
| instances.add(task);
| }
|
After task performing:
| JbpmContext ctx = workflowConfig.createJbpmContext();
| TaskInstance task = ctx.loadTaskInstance(taskId);
| Token token = task.getToken();
| task.end();
| token.signal(task.getName());
| ctx.save(token);
| ctx.close();
|
This solution is generic, modyfing process doesn't force any changes in the
client code, whats more adding new tasks requires only adding code for handling
this tasks. Of course i need some mapping between task names and Java code
(displaying some special UI forms) but this is obvious (for me).
I'm gratefull for any comments.
