I'm running into an issue where the || operator embedded in a collect isn't working as expected. My collect statement is as follows... $request : AccessRequest($name : username, $ID : sessionID, $loc : accessLocation, $day : dayOfAccess) $locationRules : ArrayList(size > 0) from collect (AccessRule((allowedLocation == "ANY" || allowedLocation == $loc)) from $group.getRules()) I don't get comilation or runtime errors but I don't the expected behavior either. That is, I don't get the intersection of AccessRules that have allowedLocation equal to ANY or allowedLocation equal to the bound $loc variable. Instead, the empty set is returned. When I modify the rule to look like $request : AccessRequest($name : username, $ID : sessionID, $loc : accessLocation, $day : dayOfAccess) $locationRules : ArrayList(size > 0) from collect (AccessRule(allowedLocation == $loc)) from $group.getRules()) I get the expected output. However, when I modify the rule to look like $request : AccessRequest($name : username, $ID : sessionID, $loc : accessLocation, $day : dayOfAccess) $locationRules : ArrayList(size > 0) from collect (AccessRule((allowedLocation == "ANY")) from $group.getRules()) ...it returns the empty set even though there are rules that have allowedLocation set to "ANY" (i confirmed this by debugging my java code). I haven't seen any documentation that uses the collect statement this way but according to my understanding of the grammer this should work. For some reason the allowedLocation == "ANY" embedded in the collect isn't working. What's interesting to note is that the following rule works flawlessly (notice the absence of the collect statement)... rule "test" when # does the user that just requested access exist in a group $request : AccessRequest($name : username, $ID : sessionID, $loc : accessLocation, $day : dayOfAccess) $rule : AccessRule(allowedLocation == "ANY" || allowedLocation == $loc, allowAccess == "true") then System.out.println("Test passed"); end Any help on the matter would be greatly appreciated.
