Re: [rules-users] Accessing properties of an object within a Nested Collection of a Nested Collection
You wouldn't be able to query just the AutoManufacturer record though.
You'd need to perform a join across tables, e.g.:-
when
$p: Part( partVendor == "PV999999" )
$m: Model( partsList contains $p )
$b: Brand( brandModels contains $m )
$a : AutoManufacturer( brandsCollection contains $b )
then
System.out.println( $p + ", " + $m + ", " + $b + ", " + $a
);
end

Excuse my ignorance I am relatively new to Drools, can you please expand on
the following:
"...(...$p.getPartsName()...) "
This is where I am having a hard time on how to navigate into the nested
collections. Or are you saying to insert the PART, MODEL, BRAND, etc as
individual facts? How would I relate it back Automanufacturer fact?
