The fix for 1115 and fix for 1204 you're working will not help me unless 1203 is fixed, because all versions of code after 4.0.0 are affected by 1203, and it is a showstopper for me since I use JDK dynamic proxies as facts.

<br> Chris, <br><br> Do you really need to "collect" all these facts? Are you doing anything with these lists? It would be easier if you can show me the full rule, but seems to me that maybe you can avoid some or all of these collects. Remember that collect is a heavy CE, so it is always good to avoid when possible.
<br> <br> Anyway, there should be no problem if you use eval(). The problem in JBRULES-1204 only affects memberOf operator, since the fix I implemented in <a href="http://jira.jboss.org/jira/browse/JBRULES-1115" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://jira.jboss.org/jira/browse/JBRULES-1115

4.0.1 or 4.0.2-SNAPSHOT due to JBRULES-1203. Below is an actual block from my rule. I'd like to transform it into something like "TestEval2" from my example, but it is more complicated. Can it be rewritten like "TestEval2"?
<br><br> $sorties: ArrayList() from collect (AirPlanSortie(event == $currentEvent, spare == false, superSpare == false))<br> <br> $statuses: ArrayList($sortieSize: size) from collect (SortieStatus(state !=
SortieState.CANCELLED, $sortie1: sortie, eval ($sorties.contains($sortie1))))<br> <br> $launches: ArrayList(size > 0, size == $sortieSize) from collect (LaunchAircraftStatus(launched == true, $sortie0: sortie, eval($sortie0.getEvent().equals($currentEvent))))

<br> Chris,<br><br> Thanks for reporting this.<br><br> I fixed a bug in 4.0.0 (released in 4.0.1) that causes you to see the correct value for "TestEval1" in 4.0.1 and later versions. Although, at that time I missed the memberOf scenario. I know why it happens (shadow fact related), but now I need to figure out a way to fix it.
<br><br> May I ask you to open a ticket for that?<br><br> Thanks,<br> Edson<br><br><br><div><span class="gmail_quote">2007/9/18, Chris West <<a href="mailto:crayzfishr@gmail.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
