Well, catinc was my attempt at making categoryName == 'blah1' & categoryName == 'blah2' work correctly. The filters would only examine one row in the database at a time, so if a node was in category 'blah1' and 'blah2' the original filter code could never work since there is no way for a single row to equal both 'blah1' and 'blah2'. Since this was the same situation with services and the "is[ServiceName]" operator, I basically cloned that behavior to scan all matching category rows and performing logic on all matches, thus it was possible for the filter to know that a particular device was in both categories, or to use the not operator, etc. This wasn't possible with straight equality. Make sense? If there is some logical way of making it work differently I'm all for it, but I'm curious to know how you would fix it. -T _______________________________________________________________________ Tarus BALOG, OpenNMS Maintainer Main: +1 919 533 0160 The OpenNMS Group, Inc.
