How to set a process variable value when I 'signal' it?

[lojian]

Just as title…
I have a process, it has a "receive task" node which could be triggered by a "signal".
Could I set that process instance's variable before I send out the signal?

Thanks…

you can try with:

runtimeService.setVariable(pi.getId(), "procID", pi.getId())
