Task Operation API calls

[hmesha]

Hi all,

How one would initiate perform task action using the API through the task service interface? The use case here is a user would have initiated an approval or rejection action and I'd like to notify the execution to apply the action to the task and therefore the process instance will continue on.

Thanks,

Hany Mesha

You can create a simple approve/reject flow using a exclusive gateway:

..

<exclusiveGateway id="exclusiveGw" name="Exclusive Gateway" />
   
<sequenceFlow id="flow2" sourceRef="exclusiveGw" targetRef="approvedTarget">
  <conditionExpression xsi:type="tFormalExpression">${approved}</conditionExpression>
</sequenceFlow>
   
<sequenceFlow id="flow3" sourceRef="exclusiveGw" targetRef="rejectedTarget">
  <conditionExpression xsi:type="tFormalExpression">${!approved}</conditionExpression>
</sequenceFlow>

..

To finish the task using TaskService, you can do this to approve/reject:

Map<String, Object> variables = new HashMap<String, Object>();
variables.put("approved", Boolean.FALSE);

// Finish the task, passing the approved variable
taskService.completeTask(task.getId(), variables);

Does this answer your question?
