[jboss-jira] [JBoss JIRA] Updated: (JBRULES-3046) regression: spurious rule firing for exists(...) or not(...)
[
https://issues.jboss.org/browse/JBRULES-3046?page=com.atlassian.jira.plug...
]
Wolfgang Laun updated JBRULES-3046:
-----------------------------------
Steps to Reproduce:
@Test
public void testExistsIterativeModifyBug() {
// JBRULES-3046
// Rule should only fire once
String str = "";
str += "declare Fact x : int; y : int end ";
str += "rule ins when then insert( new Fact( 1, 10 ) ); insert( new Fact( 2,
20 ) ); end ";
str += "rule exornot ";
str += "when ";
str += " exists Fact( x == 1 ) ";
str += " or ";
str += " not Fact( x == 2, y == 20 ) ";
str += "then ";
str += " System.out.println( "SUCCESS" ); ";
str += "end";
KnowledgeBase kbase = loadKnowledgeBaseFromString( str );
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
int fired = ksession.fireAllRules();
assertEquals( 1, fired );
ksession.dispose();
}
regression: spurious rule firing for exists(...) or not(...)
------------------------------------------------------------
Key: JBRULES-3046
URL: https://issues.jboss.org/browse/JBRULES-3046
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: drools-compiler (expert)
Affects Versions: 5.2.0.M2
Reporter: Wolfgang Laun
Assignee: Mark Proctor
Priority: Blocker
Fix For: 5.2.0.CR1
The DRL code below results in TWO firings of rule exornot. (5.1.1: Only one firing)
declare Fact
x : int
y : int
end
rule ins
when
then
insert( new Fact( 1, 10 ) );
insert( new Fact( 2, 20 ) );
end
rule exornot
when
exists Fact( x == 1 )
or
not Fact( x == 2, y == 20 )
then
System.out.println( "SUCCESS" );
end
NOTE: If field 'y' is removed from 'Fact' and the rule patterns, the rule
fires still twice in 5.3.0, but also twice in 5.1.1.
