I'am using 5.2.0-SNAPSHOT using maven from 
https://repository.jboss.org/nexus/content/groups/public/ and i can't make it 
work...
The query still return a size of 0...

Can you share your entire project with me ?

Thanks

This seems to be fixed for 5.2.x.:

declare Num
  num : Integer
end

rule sort
when
Integer( $i: intValue )
then
insert( new Num( $i ) );
end

query numbers
$a: Num( $b: num )
end


QueryResults qRes = session.getQueryResults( numbers );
System.out.println( result count:  + qRes.size() );
for( QueryResultsRow row: qRes ){
Object obj = row.get( $b );
System.out.println( $b= + obj.toString() );
}

This produces the expected results.

Calling getQueryResults with a string not denoting an existing query returns an 
empty result set. I've updated the javadoc - thanks.

Hi,

I'am trying to use Query and i'am facing a little problem :
Given this simple rule :

package be.test.person
import be.test.person.*

query get adult
  adult : Adult( )
end

query get person
  person : Person( )
end

declare Adult
  name : String
end

rule A person over 18 is an adult
  when
Person( age = 18)
  then
System.out.println(Adult detected);
insert(new Adult());
end

Lets suppose one Person over 18 is inserted inside the working memory, the 
result of the query « get adult » is 0 (Please note the declaration of Adult 
type inside the rule)
If I create a Java class Adult (commenting the one in the .drl file) and then 
run the query again, this time the result is 1
Also, the signature of 
org.drools.runtime.rule.WorkingMemory.getQueryResults(String) says 
IllegalArgumentException when query is not found in the KnowledgeBase. This 
doesn't seems to be the case when I use a fake query name.
I'am using drools 5.1.1

Any idea on this ?

Thanks
