Re: [rules-users] Problem with 'contains'
java.util.Map does not implement Collection, which ought to be implemented
by the field to which you apply the "contains" operator.
If "contains" works with a Map, it is either a bug or not well defined or
both.
To test whether a string is a key (or value) in a Map, use
(a) if the string is a field: string memberOf (map.keySet())
(b) eval( map.containsKey(string) )

I'm using in a rule the 'contains' operator against a
Map<String,String>.
The method 'containsKey' on Map is invoke twice, first with the key then
with the value associated to the key.
The rule is evaluated to 'false'.
What can I do to prevent this behavior?
