Signaling the event to process instance and all of its sub-processes

[rmilovic]

Hi. I'm wondering is it possible and how can I signal the event to a process instance and all of its sub-process instances?

All the objects in Activiti are like this, they reflect the state at the moment of the call. If we wouldn't do that, performance would be a nightmare.

Ok, following you here.

This is where you lost me. A signal will be sent to everyone waiting for it. It's a broadcast mechanism. So why do you need to get the execution ids?

Hi. As I understood if you signal the event using the signal name only it will be sent to every active process instance that is waiting for it.
But how should you do it if I want to send it to specific process instance (ex. for each order a new process is started)? I suppose that I have to use the method which also uses execution id. Am I right?

Yes, that's correct. If you only want to signal a specific process instance, you need the execution id.
