Guvnor provides for the means to author rules, not consume them.<br><br>There's no capabilities to insert your objects (other than when writing test scenarios for your rules). This would be the realm of KnowledgeSessions and *your* application.<br>
<br>If however you want your application (you do state "...in our web frontend") to be able to retrieve either a list of objects or a single one depending on whether the ID is provided then:-<br><br>(a) I'd have thought you could simply achieve this without using a Rule Engine<br>
<br>(b) If you want to use a rule engine then: insert all YourObjects into Working Memory and use Drools Queries to achieve your need with queries a bit like these:-<br><br>query "all objects" <br> $l : ArrayList( ) from collect( YourObject( ) )<br>
end<br><br>query "an objects" (int $id )<br>
$l : YourObject( id == $id )<br>
end<br><br>Have I missed your point?<br><br><div class="gmail_quote">2011/7/6 Wolfgang Laun <span dir="ltr"><<a href="mailto:wolfgang.laun@gmail.com">wolfgang.laun@gmail.com</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
I suspected something like that, but <i>matching </i>facts of type System from Working Memory and <i>inserting </i>recreated facts of the same type isn't going to get them nearer to the GUI?<br><font color="#888888"><br>

Ok I will describe it again:<br>
<br>
We want to administrate some objects in guvnor. Every object has one id, one<br>
name and one description. We have round about 100 objects.<br>
<br>
One use case is, that all objects (id, name and description) should be<br>
displayed in a drop down box in our web frontend.<br>
The next use case is, that it has to be possible to load one object (id,<br>
name, decription) by id.<br>
<br>
My solution in pseudo code for the rule is:<br>
<br>
IF id IS SET search object and return it or return null if not exist.<br>
IF ID IS NOT SET return all objects.<br>
<br>
So I need a rule for these requirements. The rule above returns the object<br>
specified by id correctly (the id will be set with id $system.getId()).<br>
Also the rule above returns all objects from the data table. But the id is<br>
missing in every object.<br>
<br>
I hope it is clear now.<br>
Maybe my approach is wrong?<br>
