Recently I migrated a large-ish app built on Zope 3.2 to Zope 3.4. ("About time" I hear someone mumbling in the audience.) One strange difference was that TALES iterators swapped the meaning of odd and even, i.e.
<p tal:repeat="item python: [1, 2, 3, 4]"> <span tal:condition="repeat/var/odd">odd<span> <span tal:condition="repeat/var/even">even<span> </p>
produces different results on Zope 3.4 than it did on 3.2.
First, your example does not work (must be repeat/item instead of repeat/var).
Right, sorry about that.
Does anyone know why this is? Is this a bug? Should it be fixed?
Where exactly is the bug?
Zope 3.2 produces odd even odd even Zope 3.4 produces even odd even odd i.e. the meanings of "odd" and "even" have switched places. As a more concrete example, when renderin a table, the first row used to get the "odd" CSS class, but now is getting the "even" one.
The output is even-odd-even-odd. The even/odd methods apply to the current iteration number afaik - but not to the variable within the current iteration itself. Or?
Right. I'm now regretting my unfortunate example that used numbers as the items to be iterated over. Marius Gedminas -- Read what I mean, not what I write.
