[jboss-jira] [JBoss JIRA] Reopened: (JBRULES-1284) ClassCastException when using "<" constraint on field of type java.lang.Object containing data of type java.lang.Integer
[ http://jira.jboss.com/jira/browse/JBRULES-1284?page=all ]
Edson Tirelli reopened JBRULES-1284:
------------------------------------
There are still problems with alpha-hashing.
Pretend you have 3 rules:
rule "r1"
when
MyFact( object == "true" )
then
end
rule "r2"
when
MyFact( object == "Bob" )
then
end
rule "r2"
when
MyFact( object == 15 )
then
end
The above 3 rules will cause the engine to hash the values "true" and
"Bob" as strings and 15 as an Integer. Although, if the object attribute is set
to something like a Boolean object, the hashcode will never match with the String
"true" hashcode and as so will never propagate. Not sure yet how to fix that...
ClassCastException when using "<" constraint on field of
type java.lang.Object containing data of type java.lang.Integer

Key: JBRULES-1284
URL: http://jira.jboss.com/jira/browse/JBRULES-1284
Project: JBoss Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.2
Environment: Windows XP, Eclipse 3.2
Reporter: Justin Wick
Assigned To: Edson Tirelli
Fix For: 4.1.0, 4.0.4
Attachments: DroolsTest.zip
If I'm doing a pattern constraint, say "< 50" on a field, and that field
is type java.lang.Object, with a value of type java.lang.Integer, a ClassCastException is
generated at run time, although there is no compile-time error saying that this is an
illegal constraint.
See attached files for an example
