[rules-users] help on drools guvnor

[Stephen Masters]

Have you tested that the rules fire when you load them as DRL?

It would probably be worth showing us what EmployeeMap looks like and the rule which you expect to fire if there is an EmployeeMap in working memory.

The Drools version would also be useful.
