    This seems a bug. May I ask you please to open a JIRA for it and attach a self contained test showing the problem?

    At the same time, I think there is a conceptual error in your rules: no object should be changed in the LHS of the rules. This will surely cause you problems in the future, so, I strongly advise you to rethink your rules.

Hi All,

I am using drool 4.0.1,I am facing some problem in using or operator

i am using 2 maps by inserting in to working memory:
1) ErrorMap<"String","String">
2) validationmap<String,Object> 

my requirment is to generate error when rule fails for this i am taking
following steps:
1) i insert one entry in error map in when part and if that rule is success
2)i remove that entry from map and
3) at the end on the basis of this map i generates validation errors. 


import java.util.Map;
import com.IValidationField;

rule "ValueAllowed_G10.3"
when
IValidationField(attributeId =="G10.3")
$map : Map( keySet contains "ErrorMap" ) 
eval($map.put("G10.3_V","E_V_ALLOWED") == null || true)
(or Map( this["G10.2"] not in("5"))
Map( this["G10.2"] in("5")))
then
map.remove("G10.3_V ");
System.out.println("comming
here----------------------------------------->");
end

this file is giving classcast exception

org.drools.RuntimeDroolsException: java.lang.ClassCastException :
com.ValidationFieldImpl
        at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:75)
        at
org.drools.reteoo.EvalConditionNode.assertTuple(EvalConditionNode.java:141)
        at
org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple (SingleTupleSinkAdapter.java:20)
        at org.drools.reteoo.JoinNode.assertTuple(JoinNode.java:120)

but when i replace "or" with "and" operator then it is working fine:
import java.util.Map ;
import com.IValidationField;

rule "ValueAllowed_G10.3"
when
IValidationField(attributeId =="G10.3")
$map : Map( keySet contains "ErrorMap" )
eval($map.put("G10.3_V ","E_V_ALLOWED") == null || true)
(and Map( this["G10.2"] not in("5"))
Map( this["G10.2"] in("5")))
then
map.remove("G10.3_V");
System.out.println ("comming
here----------------------------------------->");
end
