[Zope] what's the equivalent of sequence-item and sequence-key in tal:repeat

[Joachim Schmitz]

Your solution is not the equivalent of the dtml-in

here/get_all_languages returns a list of tuples:

[('aa', 'Afar'),
('ab', 'Abkhazian'),
('af', 'Afrikaans'),
.....
]

and  in  dtml-in sequence-item =3D Afar and sequence-key =3D "aa" for the =
first=20
item.
repeat/lang/index returns the index-number which is "0" for the first item.

I just found the right solution:

<td><select name=3D"languages:list" size=3D"5" multiple>
<span tal:define=3D"langs here/get_all_languages" tal:omit-tag=3D"">
<option tal:repeat=3D"lang langs"
tal:attributes=3D"value python: lang[0]; selected python: test(lang[0] in=20
here.getLanguages(), 1,0)"
tal:content=3D"python: lang[1]">German
</option>

I thought I had tried that before, but apparently not. I still don't like=20
the

python: lang[1] there should be something like:

repeat/lang/1
