Body
Well, it may be appears a little bit tricky, cause this approach comes natural when managing db results set. You can refer here: <a href="http://docs.zope.org/zope2/zope2book/AppendixC.html#the-following-information-is-available-from-the-repeat-variable" rel="nofollow">http://docs.zope.org/zope2/zope2book/AppendixC.html#the-following-information-is-available-from-the-repeat-variable</a> The tal:repeat statement is very powerful and, in your case you can count on "first" variable information. Instead of a simple List of Events, try to iterate over a list of dictionaries in which you take care of isPast information. Run the following (simple and brutal) tal code... it is self explaning. <pre><code><div tal:define="past string:Past events; future string:Events to Come; richList python:[{'event':'event1', 'passed': past}, {'event':'event2', 'passed': future}, {'event':'event3', 'passed': past}, {'event':'event4', 'passed': future}]; dummy python:richList.sort(lambda x,y:cmp(x['passed'], y['passed']))"> <tal:block repeat="item richList"> <h2 tal:condition="repeat/item/first/passed" tal:content="item/passed"> Past Events or Future </h2> <a tal:content="item/event">event's url</a> </tal:block> </div> </code></pre> You can create your richList iterating on the result of a catalog call. And you can create the dictionary item seting 'passed' value according with event/end/isPast function. hope this helps.

1. COI wasn't aware of such capabilities. Thanks for pointing this out. My only problem is now to understand how to connect your idea with my current application. The following is doing: Past Events or Future as Past event

2. COyou cannot do path/path/func(). You have to write a path expression XOR a python expression. You must take a look at "tal overview" documentation before proceeding ;) BTW, it's better to delegate to a python script (or a browser view class) the task of fetching your events. After that you can create a dict like mine in order to use the "first" magic word.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
