I'm still working on figuring out what I'm doing wrong with my ZCatalog stuff. I must be doing something wrong because my catalog not only doesn't seem to reindex properly, it also tends to get corrupted every once in a while...I think I'm doing Bad Things to my ZCatalog, I just don't know what they are. I've created a BugTrack Product and test stuff that replicates the problem. You can see it in action here: http://www.oswg.org:8080/bug_tracker/ To change the item_name property of one of the items, go to "View Catalog Listing / Item Listing" and click the linked ID number. After the item is edited, go back to the "View Catalog..." page, and you'll see that the bobobase_modification_time has been updated in the "ACTUAL ITEMS" table, but not in the "CATALOG ITEMS" table. (The catalog might also just randomly break, which it tends to do...not returning all items, etc. I have no idea what's causing that, either, but I'm hoping they're related problems). My actual code, including the BugTracker Product & example folder .zexp files, is available here: hgttp://www.dria.org/bugtrack.tar.gz NOTE: in the example "bugtrack_addForm" a method "RANDOM_GEN" is used. That's just a simple dtml method that sits at the top of my zope tree and contains: <dtml-let RNDM="_.random.random()"> <dtml-let RNDM="_.int(RNDM*1000000)"> <dtml-var RNDM fmt="%06d"></dtml-let></dtml-let> I use it for generating random IDs. I also hardcoded "http://www.oswg.org:8080/" in the "bugtracker_report" method, just so you know. - deb
