but, u haven't answered my question.
i see the grouped hidden lines in the example.
i use yr terms. the condition ("snippet" in my term) can not be empty, and the
action ("cell" in my term) can be empty. in my case how should i put the
condition, when no field constraint is there? how should i put in the action?
an empty makes the condition not applicable!
the case i raised seems trivial. actually it finds many applications as
follows.
rule "main"
salience 10
when
$p : Person(age > 35)
then
// do something with persons older than 35
System.out.println("hello, " + $p + "!");
end
rule "otherwise"
when
$p : Person()
then
// ignore other persons, i.e. retract them to avoid memory leaks
retract($p);
end

Condition and action cell should not be null and should contain valid data.
If you could see a small plus sign, expand it.you should be able to see the
parameters that are passed to the rule, and both the condition and action
snippets.
And the data set you are comparing against can be empty.
Hope this works for you :)
Thanks,
