[rules-users] question on drools and method calls on facts

[Garner, Shawn]

I'm under the impression that in the action clause of a rule you should only do one of the following:
1) Set a property on a Fact
2) Retract a Fact
3) Insert (Assert) a new Fact
4) Modify an existing Fact

However in some of the examples in the documentation it shows calling methods other than bean property getters and setters.
I was wondering if what other peoples opinions are on whether you should be doing more than the 4 things I listed above in a then clause of a rule.

Thanks,
SG
