Hi all,<br>
I am facing a problem with persisted stateful knowledge session, please help me. My rule is listed as below:<p>
package com.sample<br>
import com.sample.Event;<br>
import java.util.List;<br><br>
declare Event<br>
@role(event)<br>
end<br><br>
rule "test"<br>
when<br>
$list : List() from collect(Event() over window: length(2))<br>
then<br>
System.out.println("----print out in rule, size of the list collected from window is:" + $list.size());<br>
end</p>
The problem is,<br>
<ul>
<li>when use a normal stateful session(created by the calling kbase.newStatefulKnowledgeSession()), <b>when a third fact inserted, the session working memory only retains list of 2, as expected.</b>
</li>
<li>when use a persisted stateful session(created by the calling JPAKnowledgeService.newStatefulKnowledgeSession()), insert 2 facts first. Then restore this session by JPAKnowledgeService.loadStatefulKnowledgeSession(), and <b>insert a third fact, the session working memory grows to list of 3?</b>
</li>
</ul>
By the way, I am using version 5.2.0.Final. And after I upgrade to version 5.4.0.Final, the test result of persisted session becomes to normal.<b>The attachment is my test program and you can repeat it.</b><br>
I want to ask you if there is something missing that I need to do in 5.2.0.Final?<br>
Thank you in advance, any help will be appreciated. <a href="http://drools.46999.n3.nabble.com/file/n4019766/drools-session-persis-demo.zip" target="_top" rel="nofollow" link="external">drools-session-persis-demo.zip</a>
