--------------------------
I have modified my application to allow adding/removing/updating rules during
runtime. However, when I add a new rule to the rulebase, I don't get the
behavior I expect.
First, as soon as I call RuleBase.addPackage(), the new rules fire (the RHS code
runs). Shouldn't that happen only when I call fireAllRules()?
Second, newly added collect() rules don't collect already asserted objects. New
non-collect rules can see the objects just fine.
Attached is a testcase, and below is the output it produces. Am I doing
something wrong, or is this a bug? I'm running Drools 4.0.3 on JDK 1.5.0.13.
Start
RuleBase created
Adding rules about 'tom':
package rules;
import java.util.ArrayList;
import test.Tester.Record;
import test.Tester;
rule "Collect tom"
when
$list : ArrayList(size > 0) from collect( Record(field1 == "tom") )
then
Tester.show($list, "Collect tom");
end
rule "Non collect tom"
when
$rec : Record( field1 == "tom" )
then
System.out.println("Find 'tom' " + $rec.dump());
end
inserting record 1:"tom",
inserting record 2:"fred",
inserting record 3:"harry",
inserting record 4:"fred",
inserting record 5:"ed",
inserting record 6:"tom",
inserting record 7:"sreeni",
inserting record 8:"jill",
inserting record 9:"ralph",
inserting record 10:"tom",
fireAllRules()
Find 'tom' 10:"tom",
'Collect tom' collected 3 records => 1:"tom", 6:"tom", 10:"tom",
Find 'tom' 6:"tom",
Find 'tom' 1:"tom",
adding rules about 'fred':
package morerules;
import java.util.ArrayList;
import test.Tester.Record;
import test.Tester;
rule "Collect fred"
when
$list : ArrayList(size > 0) from collect( Record(field1 == "fred") )
then
Tester.show($list, "Collect fred");
end
rule "Non collect fred"
when
$rec : Record( field1 == "fred" )
then
System.out.println("Find 'fred' " + $rec.dump());
end
==> Why do the new rules fire when added?
Find 'fred' 4:"fred",
Find 'fred' 2:"fred",
'Collect fred' collected 0 records =>
==> Why doesn't the collect rule collect? The non-collect rule works.
fireAllRules()
Changing record 3 to 'fred'
fireAllRules()
Find 'fred' 3:"fred",
'Collect fred' collected 1 records => 3:"fred",
==> Why does the collect rule not see the other two 'fred' records?
