[rules-users] Using Guvnor rule to check if page is in a list of pages (enumeration)? Contains?

Hi, I'm investigating Drools Guvnor for use as both entitlements and business rules where "entitlements" means I am checking access to certain web pages (or partial page resources) based on a pre-defined a resource (given a role for example) that I would send in when executing the rule. Is it possible to populate my Fact with the resource for the left hand side and have the rule check to see if that value exists in the right hand side (presumably populated from an Enumeration). So far it seems to want me to pick a value. Instead, I want to say that any of these values are OK. I guess I'm asking if it can do a contains rather than equals from a list. Fact example: Fact name: Resource field: resourceName Enumeration name: Resources 'Resource.resourceName': ['somedirectory', 'foo/bar.html', 'etc/blah.html'] Rule Example: When There is a Resource.resourceName 'contains' a value from Resources Then Permit = true (or similar) Sorry if this is covered in the manual and I missed it. Using Guvnor 5.1.1. Thanks! K
