[rules-users] How to obtain the object/fact created in the rule file?

[Wolfgang Laun]

A global List object maintains order and can be modified by Java code, none
of which is guaranteed with a query, which incidentally adds some overhead
to Rete.

Not knowing what the ultimate purpose and destination of the FieldResults
facts is, it is difficult to suggest. Perhaps it isn't even necessary to
insert them as facts?
