Hi, I am having problems with getting back data from ZCatalog. I create instances of the ZClass "racedate". racedate has a property called "date_sort" which is the date that the race will take place in the format "yyyymmdd". In a dtml-document I read the objects with <dtml-with "admin.racedates"> <dtml-in "Catalog(sort_on='date_sort)"> <dtml-var date_sort> [...] Everything works fine until two or more objects have the same value in date_sort (eg. 20010528). Then it miserably fails. Only part of the objects or even none are displayed. I tried back and forth and it really seems to be the sort_on='date_sort'. If I do sort_on='id', all objects are displayed and <dtml-var date_sort> shows the right values. So the problem really seems to be the sorting on an index when 2 or more objects have the same value for that property. Is that a bug or a feature?
