You may have to phrase your question more accurately in order to get an answer.
Do you want the rule to fire if some, or if all, value fields of the
AwaitingAction have some value? Once or for each AwaitingAction? Or do you want
it to fire once if at least one, or if all, AwaitingActions of all
AwaitingActionLists have a field value with some specific value?
Also, would you consider inserting also the AwaitingAction objects as facts,
not only the AwaitingActionList?

[rules-users] 5.6.0.CR1 gives a NullPointerException in after evaluator
Hi everyone,
I tried to switch from 5.5.0.Final to 5.6.0.CR1 and got a null pointer
exception in the evaluation of the after evaluator.
(Exact method is:
/org.drools.base.evaluators.AfterEvaluatorDefinition.AfterEvaluator.evaluate(InternalWorkingMemory,
InternalReadAccessor, InternalFactHandle, InternalReadAccessor,
InternalFactHandle)/ )
When debugging, the exception occurs at the very first line of the method,
in:
/if ( extractor1.isNullValue( workingMemory, handle1.getObject() ) ||
extractor2.isNullValue( workingMemory, handle2.getObject() ) ) {
return false;
}
/
The cause of the exception is that handle1 is null.
The rule where the exception occurs looks like:
/MyFact(
fromdate before[ 0d ] $min,
( todate == null || todate after[ 0d ] $max ) )
/
When the exception occurs, /MyFact.fromdate/ is not null, /$min/ is not
null, /MyFact.todate/ is null, /$max/ is not null.
In AfterEvaluator.evaluate : /extractor1/ refers to /MyFact.todate/,
/extractor2/ refers to /$max/, /handle1/ is null, /handle2/ refers to the
fact including the attribute to which /$max/ variable is bound to.
Of course, this worked fine in 5.5.0.Final.
I couldn't test this out in Drools 6.0.0.CR5 because I have dependencies to
drools-spring JAR that does not exist anymore in 6.0.0.CR5.
Is it simple to fix this problem?
Thanks in advance.
Best,
Alexis

Re: [rules-users] How can I iterate through the ArrayList
rule fire for each AwaitingAction
when
$aal: AwaitingActionList()
$aa: AwaitingAction() from $aal.getAwaitingActionsList()
then
System.out.println( $aa.getStatus() );
end
Or you can itrerate over the list on the RHS:
rule fire for each AwaitingActionList
when
$aal: AwaitingActionList()
then
for( Object obj: $aal.getAwaitingActionsList() ){
AwaitingAction aa = (AwaitingAction)obj;
System.out.println( aa.getStatus() );
}
end

[rules-users] Drools 5.5 Property Reactive on Maps
So I have an object with a map like follows:
protected ConcurrentMapString, Double accumulations = new
ConcurrentHashMapString, Double();
I wrote a convince method on the class that will look up the value in the
map and add to it if it exists and
if not there will put it in the map:
@Modifies({ accumulations })
public void addToAccumulation(String code, long volume) {
if (accumulations .containsKey(code)) {
Double value = accumulations .get(code) + volume;
accumulations .put(code, value);
} else {
accumulations .putIfAbsent(code, new Double(volume));
}
}
I have a rule to listen on the change of this filed on the object(i.e
accumulations[someCode]!=null) but
when I modify the object the rule doesn't fire. I have added
@PropertyReactive to the Object and build the kbase as follows:
Properties props = new Properties();
props.setProperty(drools.dialect.java.compiler, JANINO);
KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory
.newKnowledgeBuilderConfiguration(props);
config.setOption(PropertySpecificOption.ALWAYS);
Any insight into why this may not work?

Re: [rules-users] Drools 5.5 Property Reactive on Maps
So if the property lives in the parent abstract class and that is where the method existed. If I move the method to the child with the annotation @Modifies it works. Any ideas why putting that in the parent abstract would not be honored? -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-5-Property-Reactive-on-Maps-tp4026782p4026783.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
