[rules-users] Drools all lhs execute before all the rhs, i want to run sequentially

[Wolfgang Laun]

It seems to me that you should write this as a plain old if/then/else/if...
in Java (or any other language). Or is there something else in the way
Drools evaluates rules over facts in working memory that makes it highly
desirable to use rules?

This has been asked before, and more often than not there was a way to avoid
a way of establishing the sequence of RHS execution by salience or whatever.


So, if you do need rules, you can assign decreasing salience values to all
your rules. To terminate, either call the engine's halt() method, or retract
the fact(s) triggering the rules. But note that all conditions will be
evaluated before the first RHS is executed. To aoid this: see the 1st
sentence.
