[rules-users] RE: trivial case in xls

[Bin Shen (BA/EDD)]

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,
