<br> Hey Dirk,<br><br> Trunk already supports || and && without sub-rule generation.<br><br><br>rule "severe bugs for which a member of your group is dev or support owner"<br>when<br> $group : UserGroup( )
<br> $badBugs : List() from<br> collect( Bug( (devOwner memberOf $group || supportOwner memberOf $group),<br> severity == "hair-on-fire" )<br>then<br> $group.runAroundInStarkRavingPanicOver($badBugs)
<br>end<br><br> Just remember that collect is heavy. :) Other than that you are fine. And use || and && for connecting constraints (no sub-rule generation) and "and" and "or" for connecting CE's.

In my ongoing efforts to abuse Drools syntax, I would like to write rules like this:<br><br>rule "severe bugs for which a member of your group is dev or support owner"<br>when<br> $group : UserGroup( )<br> $badBugs : List() from
<br> collect( Bug( (devOwner memberOf $group or supportOwner memberOf $group),<br> severity == "hair-on-fire" )<br>then<br> $group.runAroundInStarkRavingPanicOver($badBugs)<br>end<br><br>Will that work? Is that the right syntax? Will it be performant if I've got
<br>10000 Bugs and 1000 UserGroups?<br><br>According to Mark's "What's New in JBoss Rules 4.0" presentation, you can use &&<br>and || without subrule generation, and I have a vague memory of seeing something
<br>about "and" & "or" as well, but I can't remember where I saw it.<br><br>Thanks.<br><br>--<br>Dirk Bergstrom <a href="mailto:dirk@juniper.net">dirk@juniper.net</a><br>_____________________________________________
