Your example has openned my eyes to a few facts

You're welcome ;-)

rule "policyDefinition.Coverage"
agenda-group "policyDefinition"
when
$p : Policy()
$cov : Coverage() from $p.coverageList
then
try {
insert($cov);
}
catch (Exception e) {
e.printStackTrace();
}
end

Huh! This is one for my collection of anti-patterns!

Thanks for the feedback!
