[rules-users] How handle exception thrown while looping in DRL file

[rules-users] Counting events / fact condition not evalauted with accumulate
Dear contributors, this simple rule should trigger only when a critical amount of particular events was detected, though it seems to accept any event of this type, disregarding the fact condition (e.g. there is no single event that matches target == Long.MAX_VALUE). The current behaviour results in an unconstrained type match: LocalizationEvent(): // annotation for external event class declare LocalizationEvent @role( event ) @duration( dur ) @timestamp( time ) end // triggers on *any* LocalizationEvent, regardless of fact condition rule Detect crictial number of events when accumulate( // there is no matching event $ev: LocalizationEvent(type == TYPE.LEFT, target == Long.MAX_VALUE, area == Long.MAX_VALUE) over window:time(30s) from entry-point events/localization; $n : count( $ev ); $n 5 ) then System.out.println($n+ events detected ); end The KB is configured for stream processing, the events are inserted in a chronological order and the session pseudo clock is advanced accordingly. Drools version in use is 5.4.0. Any suggestions are appreciated!

You haven't asked any questions, merely stated you have an error message. Try posting some supporting code (DRL, related Java etc) it might help people.

Re: [rules-users] How handle exception thrown while looping in DRL file
Sorry Mike,Laune
I am handling 100thousand records for that i am using CSV file and
converting those records into objects which i am using for further
calculation.
According to my requirement i have loop array inside DRL file
So i wrote following code in .java
* agCsv.setPolCounterList(polCounterList);
agCsv.setAgentList(agentListArray);
// local block end for
policy---
//firing all rules from here-
ksession.fireAllRules();
//after firing rules destroying session object
ksession.dispose();
*
after this i am executing following rule DRL file
*rule Loop Test
salience 50
when
$a:AgentCSVBean()
then
for(Integer agentList: $a.getAgentList()) {
System.out.println(--sam=+agentList);
}
end*
Now above loop execute absolutely well but after finishing loop it throws
Error

When you say the loop works fine, do the System.out's print what you expect?

Add an if statement testing for a List element being null, e.g.,
for( Integer agentList: $a.getAgentList()) {
if( agentList != null ){
System.out.println(--sam=+agentList);
} else {
System.out.println( null element in list );

Add println() before and after the for(){...} statement. What is the output?
How many AgentCSVBean() are inserted?
Could one of these have a field agentLsit that is null?

Re: [rules-users] How handle exception thrown while looping in DRL file
Hi Laune,
I do wht u asked me, I added print statement before and after for loop
* System.out.println(Before);
for(Integer agentList: $a.getAgentList()) {
System.out.println(-==-);
if($a.getAgentList() != null ){
System.out.println(--sam=+agentList);
}
else{
System.out.println(null);
}
}
System.out.println(after);*
Before is getting printed twice and After only once.Then it prints
Error message which i mentioned in catch block from where i called rule in
java.
in following order message getting printed
* before
list of data
after
before
error*
/im printing 128thousand records/
*
No their is no null field in given records...

Please be more specific.
Add another if statement before the for statement testing whether

System.out.println( List is null );

Then it prints

}
for(Integer agentList: $a.getAgentList()) {

System.out.println(after);*
Now Execution order is

Re: [rules-users] Drools Planner changing problem fact
last month, Ralph wrote: /All the examples in the drools-planner-examples seem to have a fixed list of problem facts (rooms, teachers, timeslots) which only should be combined optimally./ Just to address this one unanswered point. The Cloud Balancing example does support changing the problem facts, specifically by removing computers (bins). The last section of the planner documentation (section 12.4) addresses realtime planning, through the Solver.addProblemFactChange() API. This works whether you are removing problem facts (as the example shows) or modifying their contents. This generally restarts the Solver -- but, if you are relatively optimized, the adjustment is found relatively fast. (I'm curious, though -- does the Solver expressly prioritize doing moves associated with those problem facts that were just changed?) -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Planner-changing-problem-fact-tp4018087p4018742.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
[rules-users] DSL translatio problem for !ucfirst under 5.1.1
I have solved this problem before, and think it is a JAR issue, but can't
seem to remember which JAR solves my problem. The DSL sentence
[consequence][]Set {field} of {object} to
{value}={object}.set{field!ucfirst}({value});
is not working since !ucfirst is being ignored. I am using 5.1.1 because of
a reoccurring bug with the in-place DSL editor of more recent versions of
DROOLS (there are JIRA's opened, closed, reopened and commented on the bug.)
What JAR would I have wrong or be missing that causes !ucfirst to not be
processed, ie converting {field} to its setter? Thanks!

Re: [rules-users] DSL translatio problem for !ucfirst under 5.1.1
IIRC I invented the ! modifiers for the DSLR substitution while Drools was
moving towards 5.2.0.
I'm not sure whether these classes could be used in an earlier context, but
the changes were quite local to the DSL/R context.
