Sigh! I don't understand what is going on.

 

I added another rule which is almost identical:

 

rule BidderReqCorrection
  no-loop
  activation-group "permissions"
when
  c: PermissionCheck(name == "stuff", action == "find", granted = false)
  Role(name == "A Role")
  AppProp(now == (new Date()), s: startDate -> (s.getTime() < now.getTime()), e: endDate -> (e.getTime() > now.getTime()) )
then
  c.grant();
  modify(c);
end;

 

But now I get the error:

 

org.drools.rule.InvalidRulePackage: Unable to create Field Extractor for 'now'
Rule Compilation error Unknown variable or type "now" Class "java.lang.Object" has no method named "getTime" Expression "now" is not an rvalue Expression "now" is not an rvalue Expression "now" is not an rvalue Exception:null

 

Its a copy-and-paste from the first rule. Just changed the action from "do" to "find".
It does not matter if I comment out all the other rules or not. This new rule always causes the error.
