why explicitly unicode type casting? can it be something else?

[spy, 2013/07/28 15:08:49]

I want to define a mapping between valid contenttype values and their human
names exactly the same way we do in 
http://hg.moinmo.in/moin/2.0/file/78ed0ce6b718/MoinMoin/templates/modify_sele...

Maybe it is not a good way to hardcode those values in the form definition. We
can check them in an appropriate validator and the mapping between some of
possible contenttype values and their names pass directly to the rendered
template.

+         for e in content_registry.groups[GROUP_MARKUP_TEXT]))
     comment_for = RequiredText.using(label=L_("Comment for")).with_properties(placeholder=L_("Item UUID"))
-    reply_to = OptionalText.using(label=L_("Reply to")).with_properties(placeholder=L_("Item UUID"))

[Thomas.J.Waldmann, 2013/06/28 22:45:30]

using "Item UUID" for both?

-    ptime = DateTime.using(label=L_('Publication time (UTC)'), optional=True)
+    reply_to = OptionalText.using(label=L_("Reply to")).with_properties(placeholder=L_("Comment item UUID"))
+    ptime = DateTime.using(label=L_("Publication time (UTC)"), optional=True)

     description = L_('Comment item')

     class _ModifyForm(Default._ModifyForm):
