Hi Wolfgang, hi Estaban,<br>
<br>
Many thanks for your insights!<br>
I'll stick to a custom accumulate function since it is more consice
than the init/action/result approach.<br>
And since I am using Drools 5.1.1, I'll create functions named
collectList and collectSet to be "future proof" :-)<br>
<br>
Best regards,<br>
<br>
Bruno.<br>

need:
<div>
<ul>
<li>collectList</li>
<li>collectSet</li>
</ul>
<div>So, your rule will look like this:</div>
<div> $countries : HashSet(empty == false) from accumulate
(City($name matches "X.*", $country : country),
collectSet($country))</div>
<div><br>
</div>
<div><br>
