Use of "exists" causes a ClassCastException
-------------------------------------------
Key: JBRULES-389
URL: http://jira.jboss.com/jira/browse/JBRULES-389
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Reteoo
Affects Versions: 3.0.3
Reporter: Edson Tirelli
Assigned To: Edson Tirelli
Fix For: 3.0.4
Using exists with later bound variables will cause ClassCastException.
package com.sample
import org.drools.Cheese
import org.drools.Person
global java.util.List results
rule "Exists with Bindings"
when
exists Cheese()
c: Cheese( $type : type );
p: Person( likes == $type );
then
results.add( $type );
end
Results in:
java.lang.ClassCastException: org.drools.reteoo.InitialFactImpl

----------
It was a regression indeed introduced in revision #3951 (don't know in which version
it was released):
- return evaluator.evaluate( this.fieldExtractor.getValue( workingMemory.getObject(
handle ) ),
- declaration.getValue( workingMemory.getObject(
tuple.get( this.declaration ) ) ) );
+ return evaluator.evaluate( this.fieldExtractor.getValue( handle.getObject() ),
+ declaration.getValue( tuple.get( this.column
).getObject() ) );
Look at
tuple.get( this.column )
instead of
tuple.get( this.declaration )
Let me know if you find any other problem.
