NPE in AbstractCompositeRestriction when using unbound variables
----------------------------------------------------------------
Key: JBRULES-2872
URL: https://issues.jboss.org/browse/JBRULES-2872
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-compiler
Affects Versions: 5.1.1.FINAL
Reporter: Wolfgang Laun
Assignee: Mark Proctor
This occurs with a pattern such as
Cell( rowNo == $rano || == $rbno, colNo != $c1no && != $c2no, free contains $i
)
where one or more of the bound variables $* are not bound in previous patterns.

Fixed in org.drools.rule.AbstractCompositeRestriction: check Declaration.getExtractor() !=
null as this is used in Declaration.hashCode

---------------------------------------
I'm not sure a declarations should ever have a null extractor, so this might just be
masking a previous error.

This is the rule triggering the error
rule has been added to org.drools.verifier.overlaps.Restrictions.drl
rule "central overlap"
when
$x: NumberRestriction( valueType == Field.INT ||

Wolfgang Laun commented on JBRULES-2872:
----------------------------------------
Sorry - the unbound variable was NOT the reason for the NPE: There were missing import.
Therefore, when you have
rule x
when
NumberRestriction( valueType == Field.INT || == Field.DOUBLE )
then
...
and Field is not imported, the NPE occurs.

Key: JBRULES-2872
URL: https://issues.jboss.org/browse/JBRULES-2872
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: drools-compiler
Affects Versions: 5.1.1.FINAL
Reporter: Wolfgang Laun
Assignee: Edson Tirelli
Fix For: 5.2.0.CR1
This occurs with a pattern such as
Cell( rowNo == $rano || == $rbno, colNo != $c1no && != $c2no, free contains $i
)
where one or more of the bound variables $* are not bound in previous patterns.
