Hi there, Many thanks for your reply. i've done as you suggest, but the problem i have is perhaps a simpler one... i don't know how to access the variable in the rules in my sub-flow. My variable is called "isManager" and i can now pass it in ok, but not use it. E.g. if i write a rule as follows: if Agent() // there are plenty of these objects in my knowledge base... then system.out.println("found an agent, and the local variable is " + isManager); i get an error "isManager cannot be resolved" ? How am i supposed to access a variable in the sub flow? (this is probably a dumb quesitons, but i just cant find out how to do it!). Thanks, Paul.

Then you also have to map it to the sub flow node. To do that, in the parent flow click the sub flow node and in the properties map the variable in "Parameter In Mapping". I hope it helps :) View message @ http://drools-java-rules-engine.46999.n3.nabble.com/Access-to-variables-f...
