Hi Steve (/me is coming up for some air, thought I would have a look on the mailing lists !).<br><br>I assume you are talking about data driven enumerations - so basically "somewhere" you have a list of values, and that is provided to users as a drop down (plus validated etc).
<br><br>This is useful for GUI stuff, but also (potentially) helpful for indexing for performance (but thats for another day).<br><br>There is a JIRA for this, for v2 of the BRMS: <a href="http://jira.jboss.com/jira/browse/JBRULES-821">
http://jira.jboss.com/jira/browse/JBRULES-821</a> would be great if you could put your thoughts down there.<br><br>I think ILog calls these "domains" - I like the term "value domain" or something like it.
<br><br>In any case, I think a variety of sources need to be provided for this: so the list of values could be part of the "ontology" (the fact model, more to come on that later) - ie some attribute of the package definition specifies a list of value. OR, perhaps it comes from an external source, like a flat file, or a database query - eg you may have some external database with Part Numbers for a Widget (!) - those part numbers may change from time to time, so it should periodically refresh the list.
<br><br>One extra feature is to be able to have name/value lists - so the name is shown, but the value applies - say you may want to display a human readable description of the part number, but the rule only cares about the value from the database.

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Firstly, just to confirm you don't think I've missed a more
obvious way of getting a set of values (say countries) into JBRMS for use in
rule conditions.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Secondly, I'm not sure I know enough yet to suggest
enhancements to JBRMS. </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Even if tables of user-defined values could be held INSIDE
JBRMS for rule conditions, it would make sense for the same tables to be
visible OUTSIDE</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">JBRMS to set the data that was being submitted to the rules.
If a rule is written for country "SPA" ie Spain, this rule would not be fired
