Split sementics with multi-instance

[workflowuser2]

Hi Experts,

I have a use-case where I would like to pass some distinct process-variable/value to "each" instance in the multi-intance.
For example:
- we collect all resources targeted in this process instance
- each multi-instance call-activiti handled "one" resource

My question, therefore, is how to pass "say resource identifier" to "each" instance in the multi-instance. Each instance will see different resource id.

Thank you, in advance.

Hi,

As described in the user guide you can do something like this:

<userTask id="miTasks" name="My Task" activiti:assignee="${assignee}">
  <multiInstanceLoopCharacteristics isSequential="true"
     activiti:collection="${myService.resolveUsersForTask()}" activiti:elementVariable="assignee" >
  </multiInstanceLoopCharacteristics>
</userTask>
The collection will contain a list of objects, where each instance will gets its own object instance.

Best regards,

Thank you, trademak.
In the example, you shown how to do this in a UserTask. Can we do the same for "call activiti" + multiInstanceLoopCharacteristics?

A callactivity also supports MultiInstance, yes.
