[rules-users] Rules and process variables...

[bob.breitling]

How do you or, even, can you access process variables in rules? 

I did this sort of thing in my rules consequences:

ProcessInstance pi = drools.getWorkingMemory().getProcessInstance(1);
((VariableScopeInstance)
pi.getContextInstance("VariableScope")).setVariable("x", x);

In my test, the process id of 1 is a bit of a kludge.  Is there a good way
to find that id?

This looks pretty ugly.

Is the right way to do this to create a subprocess and map the variable into
the subprocesses' working memory as facts with <mapping> tags?
