Re: [rules-users] Drools Multi level map access(Drools 5.5)
Hi,
due to generic erasure we cannot figure out that the outer map contains a
second map as value. That's why you have to explicitly downcast the value
returned by the first map. For instance this should work:
((Map) field[ "parentKey" ])[ "childKey" ]
I hope this helps,
Mario
