[Helma-user] New Additions to Template.js

[Maksim Lin for technical support mailling lists]

Hi Juerg,

I think it would be good to have both index and key, as the index you would want if you were pritning say numbers next to each item (say in a table).
But I think if its going to be too much trouble don't worry about it for now - if I find I really need it in the future I should have a go at adding it myself :-)
Actually at the moment I am having another go at learning to use skins again and seeing if I can do my normal dev in helmas 'default' rendering mode.

Maks.
