inside ZCatalog, but nothing to worry about. I think they are letting the sort feature out of ZCatalog now. So, instead of using sort_on inside the Catalog call, you simply use the sort feature of the <dtml-in ...> tag.
I would not think that this would be the case. Consider the example where you return Catalog results with a 'size=' parameter. In that case, dtml-in sort would sort only the subset of results returned in that Catalog call, not the whole dataset potentially returned by that Catalog search. For the latter, you have to have the sort parameter on the Catalog call. I have an issue related to this that I wonder if anyone can suggest a solution to. I have a Catalog, and a user interface that runs a search on that catalog returning potentially many pages of results. I explicitly wish the items returned by that search to be in *random* order (ie: a different order each time the seach is initiated, but the same random order during one change of linked search results pages). I wonder if it is even possible to do this and preserve lazy evaluation, perhaps by hacking on the Catalog code itself. So I'm also interested in suggestions for doining this that may not preserve lazy evaluation but do not require modifing the Catalog code. (In the early stages of deployment the average returned dataset will be less than 30 items (but still multiple pages for design reasons), so lazy evaluation is not significant at first). --RDM
