You could investigate the lists being set-up with a low salience rule and suitable declarative model (or static in a JAR):-<br><br>rule "setup"<br>when<br>then<br> insert(new Cheese("cheddar"));<br>
insert(new Cheese("brie"));<br>
end<br></blockquote><div><br>This should have a very high salience.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br>rule "likes cheese"<br>
when<br> $c : Cheese( )<br> $p : Person( likedCheeses contains $c )<br>then<br> System.out.println($p.getName() + " likes " + $c.getName()); <br>end<br><br></blockquote><div> </div><div><br>I think the request was for a check of a fact property being one out of a list. If there's just one list,<br>
you can do<br> $c : Cheese()<br> $p : Person( favouriteCheese == $c,... )<br>or<br> $p : Person(...)<br> Cheese( name == $p.favouriteCheese )<br><br>With multiple lists, you might add a distinguishing property to the list element, e.g.<br>
insert(new Cheese("French", "Roquefort"));<br>and then<br> $p: Person(...)<br> $c: Cheese( country == $p.country, name == $p.favouriteCheese )<br><br>-W<br><br><br><br><br><br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
This appears to be possible in Guvnor, although tbh I've not tried in anger.<br>

<div link="blue" vlink="purple" lang="EN-GB"><div><p class="MsoNormal"><span style="font-size: 11pt;">Hi,<br><br>Im pretty new to drools and have been going through the docs for the Expert and guvnor. I have some basic unit tests running with the rules I am trying to replicate from a legacy system. One of the rules my current system uses is to check a property in an Object against a list of values and fire if the property is present in the list ie list.contains(someValue);</span></p>
<p class="MsoNormal"><span style="font-size: 11pt;"> </span></p><p class="MsoNormal"><span style="font-size: 11pt;">I am trying to find out what the best practise is for setting up the lists which will be checked against. I don’t want to have to include these lists in java classes and upload them as facts. I would much rather be able to manage them through guvnor so my non technical users can manage them themselves without the need to release a new jar file.</span></p>
<p class="MsoNormal"><span style="font-size: 11pt;"> </span></p><p class="MsoNormal"><span style="font-size: 11pt;">Thanks.</span></p><p class="MsoNormal"><span style="font-size: 11pt;"> </span></p><div><p class="MsoNormal">
