I also tried the following rule syntax with from but without collect ( ) :
rule "Explode Globals"
ruleflow-group "Data Prep"
when
$market : Market() from request.requestObjects.values
$series : CandleSeries() from $market.candleSeries
then
insert ( $series );
insert ( $market );
end
At runtime I get an exception: org.mvel.PropertyAccessException: unable
to resolve property: values
