Wat denk je hiervan? Hello. In zope 2.10.5 (and probably 2.10.6 and 2.11 and, as I've read, all releases above 2.7) we've encountered a sorting bug in a dtml-in call when querying the catalog. I don't think it's dtml only related, but I'm not sure about that. It is the same bug as found on : https://bugs.launchpad.net/zope2/+bug/143504 Adding def __cmp__(self, other): return 0 to Products.ZCatalog.CatalogBrains.AbstractCatalogBrain seems to correct the problem though and I was wondering why this isn't added in the zope core. Does it break other stuff or should the problem fixed somewhere else? Somebody has some thoughts?
