[jboss-jira] [JBoss JIRA] Created: (JBRULES-2321) Implicit binding and "or" CE in pattern cause ClassCastException
Implicit binding and "or" CE in pattern cause ClassCastException
----------------------------------------------------------------
Key: JBRULES-2321
URL: https://jira.jboss.org/jira/browse/JBRULES-2321
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.7
Reporter: Tihomir Surdilovic
Assignee: Mark Proctor
This is a problem with Drools 4.0.7, it does not happen in Drools 5:
$factB.f1 is triggering a scenario where the engine creates an implicit biding to the
"f1" field.
That in conjunction with the use of "or" is triggering the problem
rule "implicit bindings test"
when
FactA()
$factB : FactB( $fB : f1 )
(not FactC( f1 == $factB.f1 ) or FactC() )
then
end
The exception thrown is:
java.lang.ClassCastException: com.sample.FactAShadowProxy cannot be cast to
com.sample.FactB
