[rules-dev] DRL - Local objects

Hi, I have written the rule DRL file having around 30 rules in it. Some of the rules do intermediate calculation and those calculation result is expected in the other rules in same DRL file. I can do this by modifying the facts objects in one rule and get the value in other rule. However, modifying the facts object rebuild the RETE tree and affects the performance. Is there any way by which I can pass the data across the rules in same DRL file without rebuilding the RETE tree. (I am more concerned about the performance) Thanks, Adhir
