[rules-users] Drools Flow process question...

[Mauricio Salatino]

That's because you are evaluating a Process Variable as a fact.. and it's
not a fact. You cannot do:
i : FooInstance(action == 'EDITING')
Because inside the working memory there is no FooInstance.
If you want to do that.. you should insert the FooInstance instead of
defining it as process variable.
You also has the possibility to evaluate ProcessVariables in rules.. for
that you should get the process variable from the WorkFlowProcessInstance.
Greetings
