Assign users to Human Task during runtime

[pgoncalves]

I've already searched a lot, but I was unable to understand how can I do this.

I have a very simple workflow:

Begin -------------> Human Task (swimlane = "ht_approvers") -----------------> End

I want to evaluate the users that can perform the HT during runtime, so I assigned the swimlane to "ht_approvers".

I would like to have something (listener, handler, ??) that enables me to, in a java class check the value of the swimlane and add assignees to the task based on that value.

Thanks

One way of achieving this would be to define the actor/group id of the task to variable and have other node (or on-entry/on-exit script) to evaluate the required logic and assign proper value to the variable that next will be used by the user task.

Thanks Maciej.

Is there a way to delegate the script to a java class?

I'm not comfortable in having a large script in the process definition.

In jbpm4 (if I'm not confusing with other engines ), we can simply put the classpath of a java class in the script (org.myapp.MyClass), and implement some interface in MyClass.

I'm aware that jbpm5 works completely different, but just asking...

Thanks

you can use service task that does pretty much same as it was in jbpm4 - invoke a defined method of a java class. Take a look at the example here.
