I've got a class with a field of type HashMap<Point, Double> persisted with the @Basic annotation Is there a way to write a query that checks for the existence of an Point, say (0,0) within the map and if so can I also write a query based on the value it matches to? If not, can I query an array based on the value at a given position? Oh, I'm using the 2.1.1 release with Derby Thanks Alex --Apologies if this email is repeated, I sent the original one from an account that wasn't subscribed to the list
