[Zope3-dev] use of ':action' in button names

[Garrett Smith]

I noticed that this pattern:

  <input name=3D"delete.html:action" value=3D"Delete" />

is still supported in Zope 3 TALES, but isn't used anywhere. Is this a
deprecated feature?

If it's still supported, there might be a bug lurking -- it appears that
the context's absolute URL is missing a path element when a POST is made
using ':action'.

I can provide more info if someone's interested.
