[rules-users] How to get value of global variable from one rule to another

[Edson Tirelli]

   Alexander,

   Remember that the LHS is always evaluated at assert time and RHS is
always executed at rule firing time. So, when you change something at rule
firing time that you want to cause a reevaluation of the LHS, you must
notify the engine calling "modify":


map.put("result",res);
map.put("result2",res2);

modify( map );


    []s

Also, I've tried to map these values in the
