Problem with memberOf and/or eval used in collect statement
-----------------------------------------------------------
Key: JBRULES-1204
URL: http://jira.jboss.com/jira/browse/JBRULES-1204
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.1, 4.0.0.GA
Reporter: Chris West
Assigned To: Mark Proctor
Attachments: TestMemberOfWithCollect.zip
I'm having a problem using memberOf combined with a collect statement. My test
includes 3 rules each written to output the same results (I think), but I get different
results (depending on which version of Drools I use).
The rules are:
rule "TestMemberOf"
salience 10
when
$messages: ArrayList() from collect (Message(status == 100))
$wrappers: ArrayList() from collect (Wrapper(message memberOf $messages))
then
System.out.println("TestMemberOf: " + $wrappers.size());
end
rule "TestEval1"
salience 9
when
$messages: ArrayList() from collect (Message(status == 100))
$wrappers: ArrayList() from collect (Wrapper($message: message,
eval($messages.contains($message))))
then
System.out.println("TestEval1: " + $wrappers.size());
end
rule "TestEval2"
salience 8
when
$wrappers: ArrayList() from collect (Wrapper($message: message,
eval($message.getStatus() == 100)))
then
System.out.println("TestEval2: " + $wrappers.size());
end
The output is (by version):
4.0.0
TestMemberOf: 0
TestEval1: 0
TestEval2: 2
4.0.1
TestMemberOf: 0
TestEval1: 2
TestEval2: 2
4.0.2.SNAPSHOT (taken 9/18/07)
TestMemberOf: 0
TestEval1: 2
TestEval2: 2
The correct output should be:
TestMemberOf: 2
TestEval1: 2
TestEval2: 2
