[rules-users] Drools: to find out if a rule has been triggered or not in a rule in when clause

[Wolfgang Laun]

If you set up an event handler for rule firings, you can insert a fact
RuleHasFired( String name ) and use this as an additional pattern in the
"one rule". Make sure not to insert duplicates by keeping track of already
inserted RuleHasFired facts with a certain rule name.
