How to retrieve unfinished tasks from process instance in jbpm 5

[mduk]

I've seen a couple of examples using BAM (I think jbpm graph uses this approach). There's also a Drools Fusion approach for more control. There used to be a way in jBPM 3.x:

ProcessInstance processInstance= getProcessInstance();

//get the task management instance of the process instance

TaskMgmtInstance taskManagementInstance = processInstance.getTaskMgmtInstance();

//find the unfinished tasks

Collection taskInstances = taskManagementInstance.getUnfinishedTasks(processInstance.getRootToken());

Is there a similar way in jBPM5?

Hi,

any progress about this stuff?

This can be done using the Task Events features that I'm adding at the moment.

Stay tuned, I will post some examples soon

Pedro - we ended up doing the following. I feel like there definitely a better way as Mauricio suggested:

1. Find active nodes

2. Find all nodes after nodes in #1

3. Find all human nodes in #2

Notes on 1.:

ProcessInstanceLog processInstanceLog = jpaDbLog.findProcessInstance(new Long(instanceId))

Notes on 3.:

					while (node != null) {
						if (node instanceof HumanTaskNode) {
							list.add((HumanTaskNode)node);
						}
						connections = null;
						connections = node.getOutgoingConnections("DROOLS_DEFAULT");
						if (connections != null && connections.size() > 0) {
							node = node.getOutgoingConnections("DROOLS_DEFAULT").get(0).getTo();
						} else {
							break;
						}
					}

I hope this helps.

Ouch, that's too complicated.. but yes.. I will provide more simplistic examples.

Mdu thanks for your example, I will try it while I'm waiting for Mauricio examples.

Mauricio, then let us know when you have the examples. Where will you post them? Your blog?

Thanks

Hi Mauricio,

did you implement the examples?

thx
