This seems to be fixed for 5.2.x.:<br><br>declare Num<br> num : Integer<br>end<br><br>rule sort<br>when<br> Integer( $i: intValue )<br>then<br> insert( new Num( $i ) );<br>end<br><br>query numbers<br> $a: Num( $b: num )<br>
end<br><br><br> QueryResults qRes = session.getQueryResults( "numbers" );<br> System.out.println( "result count: " + qRes.size() );<br> for( QueryResultsRow row: qRes ){<br> Object obj = row.get( "$b" );<br>
System.out.println( "$b=" + obj.toString() );<br> }<br><br>This produces the expected results.<br><br>Calling getQueryResults with a string not denoting an existing query returns an empty result set. I've updated the javadoc - thanks.<br>

<p class="MsoNormal">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)</p><p class="MsoNormal">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</p>
<p class="MsoNormal">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.</p>
