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)

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
